My computer restarts randomly.. sometimes it's twice a day.. sometimes it's once after 3 days... and so on... the screen goes dark and the comp reboots, just as if someone pressed the reset button my cpu. It happens anytime, when my system is idling at the desktop, playing games, or surfing the net. At first, it the a restart occurs 10 minutes after startup regardless of what programs i'm running, after restarting it won't happen anymore unless i power down the comp. Now, it's just completely random restarts. I've done a memtest and a diskcheck already, can you guys help me out with the minidumps? Thanks a lot..
