Random System Restarts: Here's one for you experts!
My new computer (in sig) had been running fine for several weeks until last Wednesday. The system started randomly restarting every couple hours. Then when I went to turn it on on Friday, I got a message that a hard disk had falled out of my RAID 0 array.
I ran a few HDD utilities and decided that the RAID 0 stripe could not be saved so I deleted the array and created a new to reinstall Windows on. The drives AFIAK are perfectly okay and the bad RAID array was a RAID controller problem.
The windows setup goes perfectly fine until after it restarts into the GUI installer. At that point the system restarts somewhere between 5 seconds - 20 minutes into the install. The frequency of the restarts doesn't seem to correlate with anything at all.
After 30-40 tries at this with just about every BIOS setting and hardware config possible I got Windows to finally install. (Yes, I DID spend an entire Saturday and part of Sunday trying to fix this) I guess I just got lucky that time as the system restarted just after the install finished. There restarts still occur at random (but shorter) intervals.
Here's the weird part: The system DOES NOT restart until a Windows GUI starts running. It is ROCK SOLID in DOS and runs MemTest86 for hours without an error. As soon as Windows starts (like in the Windows install GUI portion) the restarts start.
Every piece of hardware except the mobo and processor (yes, the PSU too) has been swapped out with known good parts without affecting the problem. The CPU stays at a few degrees Celcius above ambient at all times.
Please help. I have tried just about everything that I can think of.
