Possible death of my GPU?

[Cola]

Please try the following, to rule out other factors that could be causing trouble:
- Make sure your cable between screen and graphics card is properly connected everywhere.
- Try running only with one screen
- Try another cable
- Try a different output (HDMI, DVI, VGA, DP. Whatever - just something else than you are running now.)

Of these next possible solutions, do whatever is the easiest for you. If your graphics card works fine in another PC, then it's not the graphics card that's at fault. Could be motherboard, PSU, screen or something else.
- Try another graphics card in your system
- Try your graphics card in another system


What PSU have you got?
