Hi.
Voltages 1 & 3 (below) seem quite a bit off. Should I be concerned?

The voltages on the 12V and 3.3V look a bit low. However programs often incorrectly report motherboard voltages. The only tool I trust with PSU voltages is a PSU testing tool. I wouldn't be concerned personally unless the system experiences instability or shuts down. You won't see your PSU giving exactly 12V or exactly 3.3V, the true voltage is generally ± 5%. If you actually had 14.05V on your 15V the system would either should down or have issues.

Thanks. I have been having random reboots but that seems to be more connected with a USB issue I started having. Was trying to eliminate hardware as the cause.
My dual boot system is stable on XP but has been randomly restarting on Win 7. Started after I stopped using a USB TPLink wireless adapter and plugged in a PCIe TPLink adapter. Nirsoft's USBDeview edits weren't able to fix the problem. HDD is healthy (HD Sentinel). Running Memtest86 now. May have to do a reinstall of Win 7.

If you are having random reboots then hardware is actually the only thing that could cause that. By random reboot I mean a reboot as if the PC suddenly had the reset button pressed or was unplugged from the wall. The only two things that cause that generally are failing power supply or failing motherboard. With randomly rebooting PCs the first thing I do is try a different power supply.

RAM cannot actually cause your PC to shut down without giving a BSOD.

If you suspect the PSU is the issue I recommend actually having a shop perform a diagnostic for you or borrow a PSU. You don't want to buy parts and guess. It could just as easily be the VRMs on the motherboard failing.

Thank you.

I did the second best thing to taking it for a test, I swapped my wife's PC's PSU. Hers is a 850W, mine is a 900W. The HW Monitor measured voltages for her came in on target. So far, neither PC has crashed or otherwise.
I'm not sure what to make of it other than that one of them may still go down. If its hers then I know its the PSU, if its mine then its the motherboard. I was also googling for other information and happened to read about disabling automatic restart under system recovery options. Fwiw, I did that, figured it increases my chance of hopefully getting a BSOD rather than a crash. One thing I noticed is that my Firefox was constantly asking me to update and it was always on when I crashed. I know I may be grasping at straws here but I kept it off for several hours (except now, I have updated it). I gamed a bit since I know that takes resources, to see if it will crash.

Will keep monitoring.

OCCT has a good PSU stress test tool which pushes both the CPU and GPU to max power. Sometimes with crashing you have to wait and see. If neither crashes then that wouldn't be very useful; or perhaps problem solved miraculously.
