🎮 Laptop Graphics & Gaming Problems — Brisbane
Screen Artefacts, Poor Gaming FPS,
GPU Not Detected or No Display?
We Diagnose It Right.
Most laptop GPU and graphics problems are not hardware failures — they’re driver issues, wrong GPU switching settings, or thermal throttling. We always check the cheapest causes first. For genuine hardware GPU faults — artefacts, BGA solder failure, VRAM issues — we give you an honest assessment of what’s fixable and what it costs at Underwood and Sunnybank Hills. Free diagnosis. Walk in.
The One Test That Tells You Whether It’s Your GPU or Your Screen
Before diagnosing any graphics or display problem, this single test takes 30 seconds and immediately tells you whether the fault is in your display or in your GPU. It’s the most important diagnostic step — and it prevents expensive mis-diagnosis.
🖥️ The External Monitor Test — Plug In via HDMI
Connect your laptop to an external monitor or TV using an HDMI cable (or HDMI adapter if your laptop uses USB-C). Set the external display as the active output using Windows + P → Duplicate or Extend.
If artefacts, lines, or glitches ALSO appear on the external monitor: The problem is in the GPU or GPU driver — not the display panel. The fault is generating bad image data before it even reaches the screen.
If the external monitor shows a clean, normal image: The GPU is working correctly. The problem is in the laptop’s display panel, the display cable running through the hinge, or the display connector on the motherboard — not the GPU.
If nothing appears on either screen: The GPU is likely not outputting any signal at all — hardware failure or a very early boot failure before the GPU initialises. This is a more serious diagnostic requiring professional assessment.
Integrated vs Dedicated GPU — Why This Distinction Changes Everything for Gaming
Most gaming laptops have two separate GPUs. Not understanding how they interact is the cause of a large number of “my GPU is broken” complaints we see — when the real issue is a configuration problem that can be fixed for free.
Built Into the CPU — Always Present
Intel UHD, Intel Iris Xe, AMD Radeon Graphics. Built into the processor chip itself. Uses shared system RAM (no dedicated VRAM). Very low power consumption. Designed for desktop use, web browsing, video playback, and keeping the battery alive.
- ✅ Great for battery life
- ✅ Always available — can’t fail independently
- ❌ Not suitable for modern gaming
- ❌ No dedicated VRAM
- ⚠️ Games will run on this if the dGPU isn’t activated
Separate Chip — Powers Gaming
NVIDIA GeForce RTX/GTX, AMD Radeon RX. A separate chip with its own dedicated VRAM (4GB, 8GB, 16GB). Significantly more powerful than integrated graphics. Designed for gaming, video editing, 3D rendering, machine learning, and demanding visual tasks.
- ✅ Required for modern gaming
- ✅ Dedicated VRAM for graphics tasks
- ❌ Higher power draw — drains battery faster
- ❌ Can fail independently of the CPU
- ⚠️ Must be actively selected for gaming to use it
⚠️ The Most Common “GPU Problem” That Isn’t a Hardware Fault
Gaming laptops use NVIDIA Optimus or AMD Switchable Graphics — technology that automatically switches between the integrated and dedicated GPU to balance performance and battery life. When working correctly, demanding apps use the dGPU and light tasks use the iGPU automatically.
When this technology misbehaves — which it does regularly after driver updates — games run on the slow integrated GPU instead of the dedicated GPU. The result: a laptop with an RTX 4060 getting 15 FPS in a game that should run at 120 FPS. This looks like a broken GPU but is actually a GPU switching configuration problem — a free or very low-cost fix.
How to check: Open Task Manager (Ctrl+Shift+Esc) → Performance tab → GPU 0 and GPU 1. Open a demanding game. If GPU 0 (integrated) shows 80–100% usage and GPU 1 (dedicated) shows near 0% — the game is running on the wrong GPU. This is the fix we perform before recommending any hardware work.
Signs Your Laptop Has a Graphics or GPU Problem
GPU problems span from settings issues to hardware failure. Here’s what each symptom typically indicates:
🔴 Visual Artefacts & Display Faults
Coloured pixels, blocks, or random dots on screen
Random coloured pixels (green, pink, white, black squares or dots) scattered across the screen — especially during gaming or under GPU load. Classic sign of VRAM failure or GPU chip degradation. Perform the external monitor test — if artefacts appear there too, it’s GPU hardware. If only on the laptop screen, it may be the display panel.
Horizontal lines across the screen — flickering or static
Horizontal lines running across the display are almost always GPU-side artefacts — they indicate the GPU is generating corrupted image data before it reaches the screen. Vertical lines are more commonly a display panel fault. Confirm with the external monitor test.
Black screen on startup — GPU not outputting signal
Laptop powers on (fan spins, keyboard lights, drive activity) but no image appears on screen or external monitor. The GPU has failed to initialise or is not producing output. Could be a driver failure that boots GPU into a broken state, or hardware failure. BIOS screen missing means the problem is at boot — before Windows even starts.
Screen goes black or shows artefacts specifically during gaming
Works fine on the desktop but crashes, shows artefacts, or goes black when a game starts or after a few minutes of gaming. The GPU can handle light desktop tasks but fails under full load. Classic sign of GPU thermal throttling (overheating), failing VRAM, or a degrading GPU chip that passes light workloads but fails under stress.
🟡 Performance & Gaming Problems
Very low FPS in games — much worse than expected for this GPU
The laptop has a dedicated GPU (RTX 4060, RTX 3050, etc.) but games run at 10–30 FPS that should be running at 80–120+ FPS. The most common cause: the game is running on the integrated GPU instead of the dedicated GPU. Check Task Manager GPU usage during gaming before assuming hardware failure.
FPS drops significantly after 10–15 minutes of gaming
Game starts fine and runs well, then FPS drops dramatically after a few minutes. The GPU is thermal throttling — it hits its temperature limit and reduces clock speed to cool down. The most common cause: dust in the cooling system or dried thermal paste on the GPU die. Dust clean and thermal paste replacement typically resolves this.
Games crash to desktop or BSOD during gaming
Game exits suddenly, crashes to desktop, or triggers a blue screen (often with error: VIDEO_TDR_FAILURE or TDR_VIDEO_DRIVER). Can be caused by a corrupted or incompatible GPU driver, GPU overheating, or hardware GPU failure. Driver reinstall with DDU typically resolves driver-caused crashes.
Games not using the dedicated GPU at all
Task Manager confirms GPU 0 (integrated) doing all the work while GPU 1 (dedicated NVIDIA/AMD) sits at 0–5% usage during gaming. NVIDIA Optimus or AMD Hybrid Graphics is not assigning the game to the correct GPU. Fixable via NVIDIA Control Panel or Windows GPU preferences — often a free solution.
🔵 Driver & Detection Problems
GPU not detected — missing from Device Manager
The dedicated GPU doesn’t appear in Device Manager at all, or shows with a yellow warning and Error Code 43. Can be caused by a severely corrupted driver, a failed GPU chip, a broken connection between GPU and motherboard (rare in laptops since GPUs are soldered), or a BIOS-level configuration issue. Professional diagnosis needed.
Error Code 43 on the GPU in Device Manager
“Windows has stopped this device because it has reported problems. (Code 43)” on the NVIDIA or AMD GPU in Device Manager. Most commonly caused by a corrupted driver — use DDU (Display Driver Uninstaller) in Safe Mode to fully remove and reinstall. If Error Code 43 returns after a clean driver install, the GPU hardware has a fault.
GPU driver keeps crashing — “display driver stopped responding”
Windows notification saying “Display driver stopped responding and has recovered” (or in Windows 11, screen goes black briefly then returns). Known as TDR (Timeout Detection and Recovery) events. Caused by an unstable driver version, GPU overheating, or early-stage GPU hardware degradation. Driver update or DDU reinstall often resolves this.
Screen resolution stuck at 1024×768 — can’t change to native
Screen is showing at a low resolution and the display settings don’t offer the laptop’s native resolution (e.g., 1920×1080 or 2560×1440). This happens when the dedicated GPU driver has failed and Windows is using the basic Microsoft display driver instead. Driver reinstall typically restores the correct resolution options.
Horizontal vs Vertical Artefacts — Which Direction Tells You the Cause
The direction of screen artefacts is one of the most useful diagnostic signals for distinguishing a GPU fault from a display panel fault. Here’s what to look for:
🔴 Horizontal Artefacts — Points to GPU
Lines, bands, or corrupted image data running horizontally across the screen (left to right) are generated at the GPU processing level — the image data being generated is already corrupted before it reaches the display. These appear both on the laptop screen and on an external monitor simultaneously, confirming the GPU or its driver is generating bad data.
What to do: perform the external monitor test to confirm. If artefacts appear on both screens — it’s GPU driver or GPU hardware. Run DDU and reinstall drivers first before concluding hardware failure.
🔵 Vertical Artefacts — Points to Display Panel
Lines, bands, or corrupted areas running vertically (top to bottom) are more commonly caused by the display panel itself or the eDP (display data) cable running from the motherboard through the hinge to the screen. The GPU generates good image data — the damage occurs in the display hardware after the data leaves the GPU.
What to do: perform the external monitor test. If the external monitor shows a clean image while the laptop screen shows vertical artefacts — the display panel or cable is the fault, not the GPU. This is a less expensive repair in most cases.
Every Reason a Laptop Has Graphics or GPU Problems — Explained
Graphics faults range from free driver fixes to complex hardware repairs. Here’s an honest breakdown of every possible cause:
Corrupted, Incompatible or Outdated GPU Driver
The most common cause of GPU problems — and the one to fix first before assuming anything else. Windows updates, GPU driver updates, and game launcher updates can all install incompatible driver versions. Symptoms: Error Code 43, driver crash TDR events, artefacts on startup, GPU disappearing from Device Manager. The professional fix is DDU (Display Driver Uninstaller) in Windows Safe Mode — not simply updating via Device Manager, which can leave corrupted files behind. After DDU, install the latest stable driver directly from NVIDIA.com or AMD.com.
Wrong GPU Selected — NVIDIA Optimus or AMD Hybrid
Gaming laptops with dual GPUs use NVIDIA Optimus or AMD Hybrid Graphics to switch between integrated and dedicated GPUs automatically. When misconfigured — often after driver updates — games run on the slow integrated GPU (Intel UHD or AMD Radeon Graphics in the CPU) instead of the dedicated NVIDIA or AMD chip. Result: dramatically poor gaming performance that looks like hardware failure but is a settings fix. Fixed via NVIDIA Control Panel → Manage 3D Settings → Global Settings → Preferred graphics processor → High-performance NVIDIA processor.
GPU Overheating — Dust and Degraded Thermal Paste
Gaming laptops generate significant GPU heat. When the cooling system is clogged with dust or the thermal paste between the GPU die and heatsink has degraded (usually after 2–3 years), the GPU hits its thermal limit and automatically reduces its clock speed — causing FPS drops, stuttering, and crashes. Symptoms: FPS good for 10 minutes then drops dramatically, laptop very hot to touch under gaming load, fans at full speed constantly. A dust clean and thermal paste replacement typically restores full GPU performance. Brisbane’s warm climate compresses this timeline compared to cooler climates.
Failed or Degraded VRAM Chip
The VRAM (Video RAM) chips on the GPU store texture data during rendering. When VRAM chips fail or degrade — from heat cycles, manufacturing defects, or age — the GPU generates corrupted output: random coloured pixels, blocks, and scattered artefacts particularly in games and GPU-accelerated applications. VRAM failure is harder to repair than a driver issue and typically requires board-level assessment. When it occurs at load but not at idle, thermal throttling stress testing helps confirm whether it’s VRAM or the GPU core.
GPU BGA Solder Joint Cracking
The GPU chip in a laptop is a Ball Grid Array (BGA) package — attached to the motherboard through hundreds of tiny solder balls underneath the chip. Heat cycling over years of use causes these solder joints to fatigue and crack — creating intermittent or permanent connection failures. Symptoms: GPU works when cold, fails after warming up; artefacts that worsen under load; GPU disappearing from Device Manager. Board-level repair options include reflow (temporary) or reball (more durable). See our honest reflow vs reball explanation below.
Insufficient or Unstable Power to GPU
The GPU requires stable power delivery — particularly during heavy gaming loads that spike GPU wattage. A failing power delivery circuit on the motherboard, or using an underpowered charger (wrong wattage), can cause GPU instability, crashes, and artefacts specifically under load. Gaming laptops with 130W+ chargers should never be used with lower-wattage generic chargers — the GPU may be artificially power-limited or destabilised. We check charger wattage as part of the gaming performance diagnosis.
GPU and Graphics Fixes to Try at Home Before Coming In
In order of ease. These resolve a significant portion of apparent GPU problems without any hardware repair.
1. Test With an External Monitor First
Connect HDMI to a TV or monitor. Press Win + P → Duplicate. Do the artefacts appear on the external screen too? Yes = GPU or driver fault. No = display panel or cable fault. This single test tells you which direction the diagnosis needs to go — and prevents fixing the wrong component.
2. Check GPU Usage in Task Manager During Gaming
Open Task Manager → Performance → GPU 0 and GPU 1. Start a demanding game. If GPU 0 (integrated) is near 100% and GPU 1 (dedicated NVIDIA/AMD) is near 0% — the game is on the wrong GPU. Fix in NVIDIA Control Panel → 3D Settings → Global Settings → set “Preferred graphics processor” to “High-performance NVIDIA processor.”
3. Use DDU to Clean-Install the GPU Driver
Download DDU (Display Driver Uninstaller) from guru3d.com. Boot into Safe Mode (Win + R → msconfig → Boot → Safe boot). Run DDU → Clean and Restart. After restart, download and install the latest NVIDIA Game Ready Driver or AMD Adrenalin driver directly from their official sites — not via Windows Update or Device Manager auto-update.
4. Check GPU Temperature During Gaming
Download GPU-Z (techpowerup.com) or HWiNFO64 (hwinfo.com). Run a game for 10 minutes then check the GPU temperature log. If GPU temperature exceeds 85°C regularly and FPS drops occur — thermal throttling is the cause. A cooling service (dust clean + thermal paste) is the fix.
5. Confirm You’re Using the Correct Charger
Gaming laptops require specific wattage chargers. Check the label on your charger and compare to the laptop’s required wattage (printed on the bottom of the laptop or in the manual). A 65W charger on a laptop requiring 180W will cause the GPU to be power-limited during gaming — dramatically reducing performance. Always use the original charger or a correct-wattage equivalent.
6. Restart the GPU Driver Without Rebooting
If the screen suddenly glitches or goes black temporarily — try pressing Win + Ctrl + Shift + B to restart the GPU driver without a full reboot. Windows will briefly go black (1–2 seconds) and restart the display driver. Effective for one-off driver hangs but not for persistent problems — which need DDU and a clean install.
Laptop GPU Hardware Repair — Reflow, Reball and When Neither Helps
If another repair shop has offered you a “reflow” for your GPU — here’s what that actually means and what the alternatives are. Every customer deserves to understand this before paying for any GPU repair.
🔥 Reflow — What It Actually Is
Reflow involves applying controlled heat to the GPU chip while it’s still on the motherboard, with the goal of re-melting and re-bonding the cracked BGA solder joints underneath the chip. It can restore function — but it does not fix the root cause. The solder joints have fatigued from years of heat cycling. Reflow re-melts them, but they return to the same position and will typically crack again as the same heat cycles continue. Reflow is a temporary measure — it can restore a laptop for months, sometimes longer, but is not a permanent solution to BGA solder joint fatigue.
⚙️ Reball — More Durable, More Complex
Reball involves fully removing the GPU chip from the board using a BGA rework station, cleaning all old solder balls off both the chip underside and the board pads, applying fresh solder balls via a BGA stencil, and reflowing the chip back to the board with the new balls. This addresses the root cause — the degraded solder joints are replaced entirely rather than re-melted. Reball is more expensive and technically demanding than reflow, requires specialist equipment, and is only appropriate when the GPU chip itself is physically intact and the failure mode is confirmed to be solder joint related.
⚠️ When Neither Reflow Nor Reball Will Help
If the GPU chip has internally failed — the silicon die itself has a fault rather than just the solder connections — no amount of reflow or reball will restore function. Internal GPU failure and VRAM chip failure produce similar symptoms to BGA solder joint failure but cannot be fixed by resoldering. This is why accurate diagnosis before any repair work is essential. We assess the specific failure mode during the free diagnosis and give you an honest recommendation on whether reflow, reball, or replacing the motherboard is the most appropriate path — and what the expected outcome of each option is.
🚨 An Honest Note on Laptop GPU Hardware Repair
GPU hardware repair on a laptop — whether reflow or reball — is a complex specialist service. We always check software causes (driver, GPU switching, thermal) before recommending any hardware GPU intervention. We only recommend hardware repair when software and thermal fixes have been eliminated as possible causes. And we always explain the difference between a temporary and a more permanent fix so you can make an informed decision before committing to the cost.
Why Brisbane’s Climate Makes Gaming Laptop Thermal Problems Worse
Gaming laptops are designed with ambient temperature in mind — and Brisbane’s warm climate has a measurable impact on GPU performance and thermal longevity.
☀️ Ambient Temperature and GPU Thermal Headroom
A gaming laptop’s cooling system works against the ambient (room) temperature. When an NVIDIA RTX GPU is designed to max out at 85°C, and the ambient temperature is 22°C, the cooling system has 63°C of headroom. In a Brisbane summer room at 32°C without air conditioning — that headroom shrinks to 53°C. The result: the GPU reaches its thermal limit sooner under the same workload, throttles faster, and runs at reduced performance more frequently. This is why Brisbane gaming laptops benefit especially from annual cooling services before summer (October) and from being used in air-conditioned rooms.
🌡️ Gaming Laptop Thermal Service Recommendation for Brisbane
Gaming laptops accumulate dust faster than other laptops due to their higher airflow rates — the fans run faster and for longer, drawing more air and dust through the heatsink. Combined with Brisbane’s warmer ambient temperature reducing thermal headroom, gaming laptops in Brisbane benefit from more frequent cooling services than the same laptop would in a cooler climate. We recommend a full cooling service (dust clean + thermal paste replacement on both CPU and GPU) every 6–12 months for gaming laptops used regularly in Brisbane — and specifically before the summer gaming season.
Every Laptop Graphics & GPU Service We Offer in Brisbane
From a free driver reinstall to GPU hardware assessment — here’s the complete range at both our Brisbane stores:
GPU Diagnosis — External Monitor Test + All Layers
We perform the external monitor test, check GPU detection in Device Manager, confirm GPU driver status, verify GPU switching configuration in NVIDIA/AMD control panel, run GPU-Z for temperature and clock speed data, and assess whether the problem is driver, configuration, thermal, or hardware. This systematic layered approach always confirms the cheapest possible cause before recommending anything more expensive. Always free.
GPU Driver Reinstall with DDU
Professional GPU driver removal using Display Driver Uninstaller (DDU) in Safe Mode — the correct tool for complete driver removal, unlike Windows Device Manager uninstall which leaves corrupted files. After DDU, we install the latest stable NVIDIA Game Ready Driver or AMD Adrenalin Software directly from the manufacturer. This resolves Error Code 43, TDR crashes, artefacts caused by driver corruption, and low-resolution display issues.
NVIDIA Optimus / AMD Hybrid Configuration
For gaming laptops where games run on the integrated GPU instead of the dedicated GPU — we configure NVIDIA Control Panel or AMD Radeon Settings to correctly assign the dedicated GPU to demanding applications, set the global preferred graphics processor, and verify Task Manager confirms the dedicated GPU is active during gaming. Often the most impactful performance fix for gaming laptops at essentially no cost.
Gaming Laptop Cooling Service — GPU Thermal Paste
For FPS drops after 10–15 minutes of gaming — a full gaming laptop cooling service: internal dust clean of heatsink and fan assembly, replacement of CPU and GPU thermal paste with quality compound (Arctic MX-5, Thermal Grizzly Kryonaut), and post-service GPU temperature test under gaming load. Before/after GPU temperature comparison documented. Typically reduces GPU temperatures by 10–20°C and eliminates thermal throttling.
GPU Hardware Fault Assessment
For confirmed hardware GPU failures — artefacts present on external monitor, GPU not detected after clean driver install, or persistent Error Code 43 after DDU — we perform a detailed hardware assessment: GPU stress test, temperature/clock speed analysis, VRAM stability test. We identify the specific failure mode (VRAM, BGA solder joints, power delivery) before discussing repair options. No hardware work without your understanding of what the options are.
GPU Reflow or Reball Assessment
For confirmed BGA solder joint failure causing GPU detection issues or artefacts — we assess the laptop’s suitability for reflow or reball and quote both options honestly. We explain the expected durability of each approach, the additional cost of reball over reflow, and give an honest probability assessment of whether repair will be durable for your specific laptop age and GPU. Board-level repair is only recommended when hardware failure is confirmed and the laptop value justifies the repair cost.
Our Laptop GPU Diagnosis & Repair Process — Step by Step
Software and settings first, thermal second, hardware last. No hardware GPU work without exhausting cheaper options.
Walk In or WhatsApp First — No Appointment Needed
Come in to either our Underwood Marketplace or Sunnybank Hills Shopping Town store any day of the week. Describe the symptom — artefacts, black screen, poor FPS, GPU not detected, crashes during gaming. The more specific the symptom, the faster we identify the likely cause. WhatsApp us your laptop model and GPU in advance for an initial assessment.
Free Diagnosis — External Monitor Test + GPU Driver + GPU Switching + Thermal
We start with the external monitor test. Then check Device Manager for GPU status and error codes. Then verify GPU driver state and perform DDU + clean reinstall if driver is corrupted. Then check GPU switching configuration and assign the correct GPU to gaming applications. Then check GPU temperatures under load. We work through every non-hardware cause before assessing hardware.
Clear Quote — Software Fix, Thermal Service, or Hardware Assessment
After the diagnosis we tell you in plain English exactly what’s causing the GPU problem and what the fix involves. Driver fix and GPU switching configuration — often same-day with minimal cost. Thermal service (cooling + thermal paste) — same-day. Hardware GPU assessment — we explain what the fault mode is, what the repair options are (including reflow/reball), the honest likelihood of each, and the cost. You decide with full information.
Fix Completed — GPU Performance Tested Under Gaming Load
After any GPU repair, we test with GPU-Z running during a game or GPU stress test — confirming the dedicated GPU is active, temperatures are within normal range, no artefacts are present, and FPS performance is appropriate for the GPU model. For thermal services, we document before and after GPU temperatures. You leave with measured proof the fix worked.

Why Brisbane Gamers Trust Mobile Connect With Their GPU Problems
Official Telstra Partner Since 2017
An established, authorised Brisbane business with trained technicians and real accountability. Two permanent south Brisbane stores at Underwood and Sunnybank Hills — not a mail-in service that returns your laptop weeks later.
External Monitor Test First — Always
We never start diagnosing a “GPU fault” without first performing the external monitor test. This prevents the most costly diagnostic mistake — replacing the display when the GPU is actually the problem, or repairing the GPU when the display was always the issue.
GPU Switching Config — Before Recommending Hardware Repair
We check NVIDIA Optimus and AMD Hybrid Graphics configuration before recommending any paid hardware work. A game running on the wrong GPU is the most common “GPU broken” complaint we see — and a free settings fix in NVIDIA Control Panel is the solution. We find this before charging for anything else.
Honest About Reflow vs Reball
If another shop has offered you a GPU reflow — we’ll explain honestly what that means, how long it may last, and whether reball is a more durable option for your specific situation. We don’t recommend the cheaper option without being clear about what the trade-off is.
Before/After GPU Temperature Test
After every thermal service — dust clean and thermal paste replacement — we run a GPU stress test and document temperatures before and after. You see the exact temperature improvement in numbers, not just “it should be better.” Proof, not promises.
No Fix, No Fee
If we cannot resolve your GPU problem — including after a hardware repair attempt — you don’t pay for the failed attempt. We only recommend hardware repairs we’re confident about, and we explain the likelihood of success before you agree to any paid work.

Laptop GPU & Gaming Problems Brisbane — FAQ
The questions we hear most often about GPU and gaming issues. Not listed? WhatsApp us — we reply fast.
Why is my laptop showing screen artefacts or visual glitches?
First perform the external monitor test — connect an HDMI cable to a TV and press Win+P → Duplicate. If artefacts also appear on the external monitor, the problem is in the GPU or GPU driver. Start by running DDU (Display Driver Uninstaller) in Safe Mode and installing a clean driver. If artefacts persist after a clean driver install, the GPU hardware has a fault — VRAM failure or BGA solder joint degradation are the most common causes.
If the external monitor shows a clean image and artefacts only appear on the laptop’s own screen — the problem is the display panel or its connecting cable, not the GPU. This is an important distinction because the repair approach and cost are completely different.
Why is my gaming laptop getting terrible FPS when it should be powerful?
The most common cause is the game running on the integrated GPU instead of the dedicated NVIDIA or AMD GPU. Open Task Manager → Performance → GPU while in a demanding game. If GPU 0 (integrated) is near 100% and GPU 1 (dedicated) is near 0% — this is the problem. Fix it in NVIDIA Control Panel → 3D Settings → Manage 3D Settings → Global Settings → Preferred graphics processor → High-performance NVIDIA processor.
Also confirm the laptop is plugged into the charger — most gaming laptops severely limit GPU performance on battery to preserve charge. And check the power plan: Settings → System → Power & Battery → Power Mode → set to Best Performance. If FPS drops specifically after 10–15 minutes of gaming, thermal throttling is the cause — a cooling service will fix it.
What does Error Code 43 on the GPU in Device Manager mean?
Error Code 43 means Windows has stopped the GPU because it reported a problem. The most common cause is a corrupted or incompatible driver. Use DDU (Display Driver Uninstaller) from guru3d.com in Safe Mode to fully remove the GPU driver, then install the latest version directly from NVIDIA.com or AMD.com. This resolves Error Code 43 in the majority of cases.
If Error Code 43 returns after a clean DDU reinstall — the GPU hardware has a fault. The driver is detecting a hardware problem and Windows stops the device as a result. Come in for a free hardware assessment at either of our Brisbane stores.
What is the difference between integrated and dedicated graphics on a laptop?
Integrated graphics (iGPU) is built into the CPU — Intel UHD, Intel Iris Xe, AMD Radeon Graphics. It uses shared system RAM and is designed for everyday tasks and battery efficiency, not gaming. Dedicated graphics (dGPU) is a separate chip — NVIDIA GeForce RTX/GTX, AMD Radeon RX — with its own VRAM, designed for gaming and demanding visual tasks.
Most gaming laptops have both. Technology called NVIDIA Optimus or AMD Hybrid Graphics automatically switches between them. When games run on the integrated GPU by mistake — a common configuration issue after driver updates — gaming performance is dramatically lower than expected. This is fixed in NVIDIA Control Panel or Windows GPU settings, not with hardware repair.
Why does my gaming laptop FPS drop after 10–15 minutes of gaming?
FPS dropping after a consistent period of gaming is almost always GPU thermal throttling. The GPU has reached its temperature limit (typically 85–90°C) and automatically reduced its clock speed to generate less heat. Check GPU temperature with GPU-Z or HWiNFO64 during gaming — if it reaches 85°C or higher and then FPS drops — thermal throttling is confirmed.
The fix is a gaming laptop cooling service: internal dust clean of the heatsink and fan assembly, plus thermal paste replacement on the GPU and CPU. Brisbane’s warm ambient temperatures compress the thermal headroom — gaming laptops here benefit from more frequent cooling services than in cooler climates. Typical result: 10–20°C GPU temperature reduction and restoration of full, stable FPS.
Can a laptop GPU be repaired or does it need replacing?
Driver issues, GPU switching problems, and thermal throttling are all fully resolvable without any hardware repair. For hardware GPU failures in laptops — unlike desktop GPUs, laptop GPUs are soldered directly to the motherboard as BGA chips and cannot be individually replaced. Board-level repair options include reflow (temporary re-melting of degraded solder joints) or reball (replacing all solder balls with fresh ones, more durable). If the GPU die itself has failed internally, neither option restores function and motherboard replacement is the only hardware fix.
We assess each hardware GPU fault individually and give you honest advice on which option (if any) is cost-effective for your specific laptop age and value. We don’t recommend expensive board repair for laptops where the repair cost approaches replacement value.
Why does my laptop have poor GPU performance on battery?
Gaming laptops deliberately limit GPU power on battery to extend battery life — this is intentional design, not a fault. An RTX 4060 laptop might run at 80W on charger and 35W on battery, resulting in dramatically lower FPS. Always plug in the charger for gaming. Also check the power plan: Settings → System → Power & Battery → Power Mode → Best Performance. Some gaming laptops also have a separate performance mode in the manufacturer’s software (ASUS Armoury Crate, Lenovo Vantage, MSI Center) — ensure it’s set to Performance or Turbo mode when gaming plugged in.
