    Im sorry this is my first post here.. I searched google and this was the 2nd in the results list..and frankly I liked this sites design over the first...I really hope one or more of you can help me.

    Here goes.

    My computer has been locking up often recently. At first I thought it was ram.. so I did memtest...all 4 sticks of ram are fine. Im unsure what this could be, and would love your expert advice.

    The strange thing about these lockups are that windows doesnt even see them.. the eventviewer doesnt say anything about anything failing or any warnings at all, it has to be hardware. Why do I say this? Well I checked every piece of ram in single slot mode, and the program froze! Now this is dos, so drivers arent an issue..

    When the computer freezes, it will do something random that really gets me.. my usb mouse will power down. Sometimes it will powerdown my mouse and act as if it was going to lockup...but it turns the mouse back on..and im good...sometimes for awile..and sometimes it frezes a few seconds later.

    Not everytime, but sometimes during these freezes, my second monitor wont get signal. Once both monitors lost signal... it seems to be sparatic.

    I checked mobo as well as mother board monitor temps...nothing is bad...ill go ahead and tell you what they all are as of right now.

    Case: 86 F
    CPU: 95 F
    Sensor 3: 32 F (?)


    Core 0: 1.6
    Core 1: 1.6
    +3.3: 3.30v
    +5: 5v
    +12: 11.31
    -12: -11.88
    -5: -4.98

    CpuFan: 1527 RPM

    And I have a xt850 pro, I overclocked to a XT.. (wanted the 16 pipes, and its only overclocked slightly, running at 37 degrees with an aftermarket zalman)

    Could this be a powersupply issue? I thought it might and opened up the case, unplugged all the extra fans, and it still froze.

    Im at a loss...really I am.

    PC Specs:

    p4 2.53

    2 dvd burners (one dvd RAM)

    Powersupply 430 watt 2 rails.
