Hey, I am having some trouble pc wise and im mindboggled, first off heres my pc info: Athlon 64bit 3200+ processor K8N_Neo4-F MSI motherboard 1.5gigs of memory Nvidia 7800Gt graphic card 128 mb Windows Xp Pro SP2 2x 200Gb SATA hard drives Ok here's what happened, i'm a fanatic gamer and was playing my favourite wow. All of sudden my framerate dropped from 30 to 2. I thought i'd try shutting it down and restarting to see what it did, when i tabbed back to windows all the icons were huge with choppy colours (basically like i was using some 1980's Graph. Card). Clearly something wasnt right and there wasnt much i could do but to restart my pc. So... that's what i did, only touble is it only gets as far as the windows loading screen then restarts itself, almost like key files had been deleted or something. I immediatly thought it was a virus but im not sure what virus could affect my G card like that. I just cant get it started up and i will have to format and reinstall i'm clear about that. But i would like to know what could do this so i can perhaps avoid it in the future. (EDIT: O btw, i have tried my Graphics card on a different pc and it works just fine so thats not the problem) Thanks in Advance.
