Computer gets in an endless power up/power off loop

  1. Hello all,

    I've been having a problem with my newest PC since day one. It seems that once in a while, after I put it to "sleep" it will cannot return from it's powered-down state. Instead, it will appear to power up, and you can hear the fans begin to whirl and the power light on the case comes on, but it simply cuts off after about 2 seconds. It never even gets to POST, as far as I can tell. This endless loop of powering up and cutting off will continue until I perform a hard reboot, after which everything is fine. I'm not sure if it is a BIOS issue or a software issue but if anyone has had similar problems I'd love to hear the solution!

    My current PC configuration is:

    GIGABYTE GA-EP45-UD3R motherboard
    Intel Core 2 Duo E7200
    ARCTIC COOLING Freezer 7
    EVGA 512-P3-N980-AR GeForce 9800 GT
    CORSAIR CMPSU-650TX 650W
    WD5000AAKS 500GB
    OCZ 1GB DDR2 800 (4)
    running Vista

    Thanks!

    Good specs ;) Have you tried applying a bios update or a CMOS reset?

    try a BIOS upgrade first, if that fails then do a CMOS reset
