Question that maybe someone can help me out with-

My comptuer will run stable for two days, then at random times, it will just crash... doesn't shut down, the USB and video just dies along with audio, however the comptuer still stays on and all the fans keep spinning. When this happens, if I remove the RAM from its slots and swap them around, it boots up fine and will run perfectly again.

I ran Orthos Stable at stock settings with a QX9650 for 4 hours, MEMtest comes up fine. The RAM is Corsair Dominator DDR-800 4-4-4-12... all settings are proper in bios.

This isn't killing me, but its a bit annoying. Any ideas?
