    Question [help] PC won't shutdown

    hello everybody,

    my 9-year old desktop PC is having a weird issue.

    this happens randomly, but most of the time, when i try to turn it off from the OS, it won't shutdown; it restarts/reboots instead.

    motherboard : J&W JW-A870T-UC3
    cpu : amd phenom II X4 955
    ram : 2 x 4 gbytes DDR3
    psu : seasonic 520 watt
    os : dual boot, debian linux + windows 7

    so when i try to shut it down from windows or linux, it reboots. so i have to force turn the power off from the UPS.
    but sometimes it does shutdown the PC. it is randomly, so this confuses me.

    which part of my PC is broken ? is it the PSU ?
    thanks in advance.

    It does this whether you shut down from Linux or Windows?

    yes, either from windows or linux. but it is randomly, sometimes it reboots, sometimes it does shutdown the PC.

    i did not overclock the system, but some voltages are higher than normal.

    Software voltage readings are never to be trusted. They are almost never accurate.

    If you have a DMM you could probe the cables to check the line voltages.

    Sounds like your motherboard is going South.

    I'd check for swollen capacitors, make sure the BIOS is up to date, test the RAM with MEMTEST etc, and check the voltages with a Digital Multi Meter; especially the 5V standby

    Check the BIOS battery; if you haven't changed it for 9 years it may well need replacing.

    too bad, i don't have a DMM at this moment, but i will purchase it if necessary.
