GPU diagnosis & repair

Your GPU has vitals.
We know how to read them.

Overheating, artifacts, crashes, dead VRAM — every symptom has a cause. We open the case, run the diagnosis, and treat the actual fault instead of selling you a new card.

Diagnosis

What is your GPU telling you?

Every fault leaves a signature. Match what you're seeing to the chart below — then bring it in for a proper read.

Critical

Overheating

Open task manager and check GPU temperature under the performance tab. Anything sustained above safe limits will throttle or crash the system.

Likely cause: failed fans, dried thermal paste, dust-choked heatsink
Critical

Crashes under load

The whole machine locks up or restarts specifically during games or renders — never at idle.

Likely cause: VRAM fault, power delivery failure, core degradation
Warning

Artifacts

Odd shapes, coloured static, or small frozen patches on screen during normal use.

Likely cause: failing VRAM, dying core, cracked solder joints
Warning

Stuttering & glitching

Frame delivery stops and starts, making motion feel jumpy even when frame rate looks fine.

Likely cause: thermal throttling, power instability, driver conflict
Check first

Driver issues

Outdated drivers throw errors that look like hardware failure but aren't. Worth ruling out before anything else.

Fix: update via NVIDIA or AMD
Check first

Display doing odd things

Flickering, no signal, or wrong resolution is often the cable or port, not the card itself.

Fix: reseat cables, try a different port before booking a repair

Common failure patterns

Case 01

Stuttering & glitching

The screen stops and starts quickly, making any kind of animation jumpy — even when your frame counter looks healthy. Usually a sign the card is throttling or losing power stability under load.

Fix now

Case 02

Artifacts

Odd shapes, light effects, or small frozen patches appear on screen. This is memory or core damage speaking — the earlier it's caught, the more likely a full repair rather than replacement.

Fix now

Case 03

Crashes

The entire computer crashes or restarts specifically when you push graphics-intensive tasks. Left untreated, this pattern tends to get worse, not better.
