    spontaneous reboot... voltage issues

    AMD XP 1800+
    EPoX 8KHA+
    Win XP

    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
    +3.3: 3.25V
    +5.0: 4.81V
    +12: 12.10V
    -12: 2.64V
    -5.0: 0.00V

    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.

    Gomer,
    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?
