So its been a long while since i've had this issue but somehow it came back to tickle me once more. I posted up a while ago with the same issue, here is a link: http://www.techspot.com/vb/topic124148.html Windows 7 RC Gigabyte EP43-UD3L mobo Seagate 250GB Barracuda 7200rpm SATA HDD Hitachi-LG Data Storage DVD/CD RW Model: GSA-H31N Nvidia EVGA 9800GTX+ 512mb Vid Card 2x2GB Kingston DDR2 1066mhz Intel Core 2 Duo E6600 @ 2.40ghz 20" Dell Widescreen Monitor About 5 months ago i was playing WoW and my screen fuzzed out (artifacts on speed) with mass colors everywhere (see above link for pictures). I assumed it was my gfx card so i replaced my 8600gts that came with the computer with a 9800gtx+ and the problem went away. I tested my gfx card in another computer and it ran just fine. Two days later the same thing happened and i couldnt even get past a boot up screen without the screen goin nuts (again, check pictures in above thread). So i then figured it may be the motherboard from some help online and here at techspot. I ended up buying a EP43-UD3L w/ some 2x2GB 1066 DDR2, an Antec EA650 psu, and a new case. A new case since the new mobo wouldnt fit in the dell XPS710 case. I reinstalled windows, downloaded all correct drivers, and she's been working fine till now. Three days ago i got the same fuzzed color annoying screen and since then the computer will only stay up for a few minutes before crashing again. So i put Prime 95 on the computer and do a CPU stress test and its passing perfectly. I'm pretty sure this issue is hardware related but i'm seriously running out of options on stuff to replace here. I'm really about to just go buy a new case cuz at this point im just baffled ;p kidding aside, does anyone have any clue as to what the problem might be? or something i can check? Quickly running through the above link will definately help clear up some issues as well as some things that i've already tried. Thanks!
