spontaneous reboot... voltage issues
AMD XP 1800+
My normally rock solid system just rebooted itself while browsing the web. No warning.
It hung for a bit on the reboot at the desktop.
My mobo monitor is reporting the following...
Core 0: 1.74V
Core 1: 1.50V
Do these look right? I know very little about proper system voltages. Temps were 48C, 30C

what the power supply . alot of the times rebooting is a power supply dieing issue . least it has been that way for me when it happened . can you switch it out to test it and see if that stops the problem . also i don't get the core 0 and core 1 thing . and 0 on the -5v ?"

Core 0 looks right, Idunno about Core 1. Idunno about that -5V either. Everything else looks good though. Of course it could be an intermittant problem, and those are the hardest to diagnose. I would agree, try a good quality PSU first. Next, I would try a battery back-up. That'll help "smooth out" the power coming in.

The -5v rail is responsible for serial port operation. Unplug any serial devices if you have any and check your voltages again.

I have been having the same problem, but after swapping out everything, and another new build doing the same thing I realized it was crappy power from the wall. It finally even quit working lights plugged in,,,, about the same time it caught fire.
Have a friend that can test the outlet?"Sometimes life is just what we make it."
