I am currently having an issue which I thought related to WOW but now it happens all the time. Problem one is the system crashes, screen goes black I get "no signal" on the monitor but all the fans and everything are still running on the system and the system doesn't reboot I have to switch it off to get it started again. Second problem is whilst playing games and now even when opening the browser the screen goes multi coloured. I can still see the original game or browser I have open but can't read a thing on it. I am currently running an Athlon 64 x2 5200+ 2.7ghz with 2 gig of ram and a Nvidia geforce 8800gt. I am running Vista 64 Is my system telling me the video card is shot or is there another issue with it. I have updated the drivers to no avail. I thought the system might be overheating but its now running with the side off the case and there is good airflow so I dont think it is overheating. Right now the computer will only run for 5 minutes last crash occurred whilst the control panel screen was open.
