I built two IDENTICAL systems, one for myself, one for my uncle. Everything is exactly the same, I even wired them the same (by that I mean I used the modular power cables the same in both rigs).
My uncle's computer runs great. He has had it for 2 weeks now, and says it has not froze or had any error. I ran prime95 on it for 8 hours, and it ran fine. He has ran crysis on it fine.
The rig I built for me, however, freezes when I run prime95, with no overclocking. Only setting changed in BIOS is ram voltage, which I set to 2.16v ("AUTO" was undervolting).
At first, I thought it was a RAM issue. The first thing I did was remove the 2nd 2gb stick, so I only had one stick in. I ran memtest, it passed. I booted into safemode to make sure it wasn't a driver issue, it froze. I then took a stick of RAM from my uncle's rig, and put it in mine. My rig still froze.
So I thought it was a Mobo or CPU problem, so I RMA'd them both. I got the parts back yesterday, and my rig is STILL freezing.
I don't think prime95 stresses the hard drive, so I don't think it is a HD problem, although it could be?
I don't think it is an overheating issue, because when NB or SB overheats, according to some forum posts I read, it shuts the computer down. My rig is frozen, and I have to hold the power button to get it to shutdown.
Could it be a PSU issue?
(note: Prime95 will freeze randomly. The quickest it has frozen was 5 minutes, the longest it has ever lasted was 1 hour, but it usually lasts between 10-15 min before freezing)
