I've been fighting with this problem for the last 3 weeks where my machine will just instantly reboot. No BSOD, and when i checked the event log all that was reported was the generic "Kernal-power" error with the detailed information pointing to a hard crash.

This is a machine that was working for 18 months before these crashes started happening. When they started happening is after I added 3 HDs in a RAID-5, upped the memory to 12gb, moved to a new house, added a SSD and added about 5 case fans.

I have thus eliminated the RAID, and determined that the SSD was not the cause (because it was still crashing even though the ssd wasn't connected).

I've run memtest several times over night with no memory problems showing up.

I've run IntelBurnTest to max out the cpu to see if it was a heat issue and at full tilt after 20 min it was only at 85C and the machine didn't crash. I also took a look at the voltages during this test, with a screenshot at the bottom of this post

I've ruled out a software issue by reinstalling windows 7 ultimate x64 a total of 5 times, but even during that the install it crashes. Happens sometime during file copying at the beginning, or during uncompressing files, or sometimes during running windows update.

The only discernible pattern i can see is that it seems to crash when hard disks might be spinning up or when they are accessed heavily from large file transfers.

My current guess is that it is probably an issue with the MB, PSU or the power coming through the outlet.

Any suggestions of what i could try to troubleshoot or what may be wrong?
