I'm currently running an Abit KG-7 RAID, Athlon XP 1700+, 512 DDR, Win XP Home, ATI 8500DV AIW, Soundblaster Live, etc. Up until recently, it ran great. However, a few weeks ago it began locking up during games - Crt-Alt-Del did nothing, and the only way out was to reboot. At first it was just Rise of Nations which caused crashes, and other games ran fine, but now most every game locks up 5 minutes into gameplay. I've tried different drivers for the video card, a different v-card, different sound card, and new RAM, and nothing helps. It runs fine in Windows, however; I can surf the net, check e-mail, run Word, etc., for hours, with no issues. Could this be a motherboard issue? What else should I check? Thanks in advance for any help!!
