What can cause this problem
Several faults can create the same symptom. The list below is a starting point for diagnosis, not a reason to order parts without testing.
- Driver or Windows corruption
- Overheating or failed cooling fan
- Unstable power supply
- VRAM or GPU failure
- Damaged power stage
- Motherboard slot or cable fault
Safe checks before repair
Protect important files first where the device remains stable. Stop after liquid, smoke, battery swelling, burning smells or signs of a failing drive.
- Try a known-good display cable and port
- Record whether artefacts appear before Windows
- Note temperatures and fan behaviour
- Return overclock or undervolt to defaults
- Check power connectors without opening the PSU
- Test the system with suitable comparison hardware where safe
Possible repair routes
The correct route depends on the confirmed cause, exact model, data requirements and whether a reliable repair remains economical.
- Driver cleanup
- Cooling and fan repair
- Board-level power repair
- Connector repair
- Graphics card replacement
What changes the quote
A headline price cannot account for every model, part and level of damage. These are the main factors that need confirmation.
- Card value and age
- Fault type and parts
- Diagnostic and test time
- Replacement availability
- Expected reliability after repair
Frequently asked questions
Are visual artefacts always the graphics card?
No. Display cables, monitors, memory and the system can also create image faults, though startup artefacts make hardware more likely.
Does baking a graphics card repair it?
No. Uncontrolled heating can damage the board and is not a reliable repair method.
Can a failed fan be replaced?
Often, depending on the exact cooler and part availability.
Can a power supply damage a graphics card?
A faulty or unsuitable supply can contribute to instability or damage, so system power should be checked.
