I've been having some random rebooting problems and was hoping one of you could shed some light.

I built my computer about 6 months ago. 3 months ago the display went down, and I could only see the display if I switched to the motherboard graphics, so I replaced my radeon 7970 with an nvidia 770gtx. Everything was fine.

Now 3 months later I'm getting random reboots that don't seem connected with software, and half the time when it reboots I'll lose the display for about 15 minutes. I don't get a display even on motherboard graphics, and eventually it just comes up as if nothing was wrong. But I get several of these reboots every evening.

Any suggestions as to what may be the culprit?

thank you in advance for your help!
