hey everyone,
i've been having a problem with my newly built computer freezing on me. it could happen at any time, but it usually happens when i'm playing a game in windowed mode and trying to multi-task by opening up firefox or MSN chat. it also happens occasionally when i'm just browsing youtube. when it freezes, the screen will always go black and/or it will have colored lines that look like | | | | | all over the screen. i checked my cpu and gpu temperature which both seem to be fine. while playing games, both stay under 50. i don't believe it's a virus because i had this issue about the 2nd day after building the computer, although it seems like it's been freezing more often now.
edit----
specs: ASUS m4a79xtd evo motherboard, amd phenom II x4 955 processor, ATI radeon hd 5700 series, corsair xms3 ddr3 4g, windows 7 64bit
please let me know if there is any other information anyone would like me to post. any help would be much appreciated.
