Hello, ive had this problem for a while. It faded for a while and only recently it returned. IT is quite the stressor, I have an amd a8sx motherboard with 3500+ processor. 8600 Gts nvidia graphics card, 2.5gigs ram. I restart it quite a bit only to find it didnt help. occasionally just by chance ill unplug the power to my main harddrive and it randomly works. although the harddrive doesnt seem to be the problem. I can only assume that my Graphics card is failing. I checked all the caps on it no leaking of anything from a busted "transistor" i wanna say. wiping my harddrive monthly is just a hassle. I use windows xp dark edition v7. i have 2 harddrives seagate i believe one ata? and one sata. Ok onto the problem. I start my computer and during the logo, the standard check on ram, i get massive quantities of "artifacts" i call them, Rectangular pixels that are out of whack. mixing and making letters disappear entirely. I first noticed this when I was playing Combat zone Special Forces. It suddenly Froze, making the artifacts appear. Then it started happening during movies, and more importantly... Starcraft 2....Never have i had this problem so consistent. I restart i power down they're still tehre i leave the computer off for a day i turn it on. Still there. On random occasions i have luck and it works for few hours. Im using an alternate computer source. because i cannot bear to look at it without getting mad raged. Ive swapped out ram before. but i can only assume Gfx. like i said. But nonetheless i want some lovely techi-support from whoever is kind enough to help me. Im in crisis. PLEASE HELP REQUEST INFORMATION AND I CAN GIVE TO YOU IF I KNOW HOW. OR ILL GOOGLE HOW TO FIND OUT. ahah THANKYOU!!!!
