Screen artifacts, crashes in games, or a black screen under load usually point to the graphics card (GPU). Here's how to tell a fixable fault from a failing card.
Common GPU Symptoms- Artifacts — coloured dots, lines, or textures glitching (a classic GPU sign).
- Crashes, driver "stopped responding" errors, or freezes during games/video.
- No display at all, or fans spinning at full speed with a black screen.
- Overheating and loud fans under load.
- Clean-reinstall the GPU driver (use DDU) and update to the latest stable version.
- Reseat the card and its power connectors; blow out dust from the heatsink/fans.
- Check temperatures — sustained 90°C+ means cooling needs attention.
If artifacts persist across drivers and a reseat, the GPU itself is failing — often dried thermal paste, worn fans, or (repairably) a power or memory fault on the card. Professional GPU service includes a thermal repaste, fan replacement, and in many cases chip-level board repair or reballing — far cheaper than a new card. A diagnostic confirms whether it's the card, the slot, or the PSU before you spend.
