So this morning my PC was working normally until I started a game. As the game was loading, the display on the screen started scrambling and after a couple of seconds, the PC restarted.
After restarting, there were black horizontal lines on the login screen. After logging in, the screen turned blue and it restarted again. It kept on restarting like that every time.
I booted into safe mode, uninstalled the graphic drivers using "Display Driver Uninstaller." Then, I booted the PC up normally and it booted without any problems and the display was normal. I installed the latest drivers again, restarted the PC, but the horizontal black lines reappeared again on the login screen. Now after I log in, the screen turns blue for a second and the PC restarts itself.
I've tried removing the card and putting it back in the slot again, but that didn't help. The motherboard's onboard graphics work fine. The card is over 3 years old.
So is the card dead or is there something I can do to fix it?
Specs:
Gigabyte GA-78LMT-S2PT
Phenom II X4 965 BE
Sapphire HD 6850
Power supply - Cooler Master Extreme power plus 500W
Thanks.
