Alright so I was running Prime95 last night to check to see if my overclock is stable (i7 920 @ 4ghz). I woke up this morning to see if prime95 was still running and the computer was at the log in screen (meaning it restarted). I looked in the prime95 log file and at the end of it it doesn't show an error, it just shows a pass.

According to the log it ran for about 5 hours.
I'm not sure if this means my overclock is unstable? Is there any way to see if it was because of an error that my computer restarted?

Input is much appreciated. Thanks!
