Is My Graphics Card Failing? Signs, Tests and Repair vs Replace

A failing graphics card can cause artefacts, crashes, no display problems and gaming instability, but other components can create similar symptoms.

Common signs of graphics card problems

Screen artefacts or coloured blocks
Crashes during gaming
No display while the PC powers on
GPU overheating or fan problems

GPU fault or another PC fault?

Power supply issues, RAM faults, motherboard problems and cables can look like GPU failure. Diagnosis should come before replacement.

Repair or replace a graphics card?

The decision depends on the GPU model, fault, replacement cost and whether repair is reliable.
