hey my computer just started to act up a few hours ago
the problem is that the screen is all sorts of different colors and isnt displaying properly, its not the moniter, ive checked hat by trying one from a different computer
windows still loads fine, its just the display thats all scrwed up, some time it will put random charactors on the screen, sin a random scattered pattern, the colors occasionally switch around, and once and a while the screen works normal up until a certain point and then the problems start
i first noticed this playing a game when after a while playing it would do this, and id have to reboot
now its doing it pretty much all the time, even in the POST and the BIOS screens
i have a Geforce 8500 GT graphics card and an AMD Athlon 64 dual core processor on a mach speed MSNV-939 board
could it be that i overheated something? a BIOS virus?
Does your motherboard have onboard graphics? If so, disable your dedicated card, and its drivers, and plug your monitor into the onboard output and see if it works, if it does, I think you should invest in at least an HD4850.
You're getting what they call artifacts. Open up your computer case and make sure that there's nothing in the video card's fan. Try playing some intensive games for a bit with your case open, if that solves the problem it's overheating. If it doesn't I would say your card is defective and you should try to warranty it.
