Just recently I was playing Men of Valor untill my computer restarted, I thought it was no problem and just shut of my computer and went to sleep. The next morning I woke up and my CMOS battery was reset so I put back the boot sequence and started up Windows. I try to play Men of Valor again and after a couple of minutes a blue screen pops up for a split second and my computer restarts. My computer keeps restarting when I try to play my games. I've just recently upgraded some parts on my computer; I replaced my Ti4200 64mb to a Ti4400 128mb and added 256mb (making my total memory to 768). Anyone have any ideas to what is causing my computer to keep restarting? My computer specs: Windows XP Pro Athlon XP 1800 (stock cooling) @ 1.15Ghz 756MB of RAM 350 watt power supply Thanks.
