Graphics card repair in Watford: no display or artifacts?
Quick answer
No display or artifacts?
Graphics card repair in Watford covers dead cards, screen artifacts, driver crashes and fans that never spin, with board level diagnosis before anyone talks about replacement. A graphics card is usually the most expensive part in the machine, so it is worth diagnosing properly.

Many faults are power delivery, thermal pads (soft pads that carry heat away from chips) or a seating problem rather than a dead GPU core.
Graphics card repair in Watford: common graphics card faults
These are the GPU symptoms we see most often from gamers and creators.
| Symptom | Likely Cause | Our Fix |
|---|---|---|
| No display at all | Card or slot fault | Bench test and reseat |
| Coloured artifacts | Failing memory | VRAM diagnosis |
| Crashes under load | Power delivery fault | VRM and PSU testing |
| Fans not spinning | Fan or header failure | Fan replacement |
| Very high temperatures | Dried thermal pads | Re-paste and re-pad |
Quick checks before you call
- Try the card in another slot or another machine if you can
- Check both power connectors are fully seated
- Note whether artifacts appear in games only or on the desktop too
- Watch whether the fans spin up at power on
- Test with the onboard graphics to rule out the monitor or cable
If you are unsure what is wrong, our specialists will diagnose it properly rather than guessing. You can also check the manufacturer support pages for known driver and firmware issues before you book, but if the fault is hardware we will find it and fix it.

Graphics card repair: your questions answered
Can a graphics card actually be repaired?
Often yes. Fan failures, thermal pad breakdown and power delivery faults are all repairable. Failed GPU cores and dead memory usually are not.
What causes artifacts on screen?
Artifacts normally point to failing video memory or severe overheating. We test the memory separately to confirm which it is.
Is it worth repairing an older card?
We give you the repair cost against the replacement cost and let you decide. There is no pressure either way.
Do you test the card on its own?
Yes. We bench test the card outside your system so a motherboard (the main circuit board) or power supply fault cannot be mistaken for a GPU fault.
Why graphics card repair is worth doing right
Replacing a graphics card on a guess is an expensive mistake. Proper testing tells you whether the card is repairable first.
Repair before replace
Fan, thermal and power faults are commonly repairable at a fraction of a new card.
Board level diagnosis
We bench test the card separately from the system so the result is not clouded by other faults.
Honest verdict
If a card is genuinely beyond economical repair we say so, and no fix means no fee.
