Graphics card repair in Hemel Hempstead: no display or artifacts?
Quick answer
No display or artifacts?
Graphics card repair in Hemel Hempstead starts with one question, whatever the fault (no display, screen artifacts, crashes or overheating): is it the card or the rest of the PC? A faulty graphics card can cause everything from a blank screen to weird visual glitches, but some GPU faults are repairable, though often a replacement is the better call.

Graphics card repair: your questions answered
Can a graphics card be repaired?
Some GPU faults are repairable, such as cooling and connection issues. We diagnose first and advise honestly on repair or replacement.
What causes screen artifacts?
Artifacts often mean failing GPU memory or overheating. We test the card to confirm the exact cause.
My screen is blank, is it the graphics card?
It could be. We test the GPU, connections and other components to identify the real reason for no display.

Yes. If a repair is not viable we can supply and fit a suitable replacement GPU for your system.
