    Start computer up and it automatically turns off after about 5-10 seconds. I mean from point of turning on, fans go on for a few secs and that's it, never have time to get anything on the monitor
    Put in a brand new out of the box 600W Ultra power supply, tried 4 different power cables, 2 different outlets.
    No CD/DVD drives hooked up, just the HD.

    What are some other possible reasons for this happening? MB? Memory stick?

    Highly possible that he problem is the motherboard. Disk would not cause the computer to shut down neither would the graphic card or the processor. Power problems i think so if you tried a completeley new PSU only the mobo remains.

    If you have a chance, try the processor, ram and graphic card on an other mobo, then you will see if the mobo is the case.

    yeah right now I'm with the heat problem also make sure pc is completely clean on the inside, especially the heatsink, make sure it is still mounted to the cpu socket/mb securely.
