I installed a 6800GT in my uncles in december. It worked great untill about a month or so ago when everything just went crazy. At boot all the letters were totally scrambled, as well as having seemingly random letters all over the shop. I know the mobo was faulty so i replaced that but nothing changed.
The problems seemingly only started after Everquest 2 was installed (Coincidental?), before that it worked fine. The card has never been overclocked as far as i know (namely because my uncle doesnt know what overclocking is).
I ran PC-Check and the CPU, Mobo and memory are fine, i also ran Memtest after to check again.
Does anyone know what might be causing the problem?
