Computer spasmatically turns off

Ok. so i've got this rig running (new/upgraded): Nvidia Galaxy 650i ultra mobo, Evga 8600GT 256mb, 1GB RAM, coolmax 500w powersupply, Celeron D @ 3.06ghz. When i start the computer, everything SEEMS fine. Heres the issue: after about 45 seconds to 1 min of running (i dont have any OS on it, just the bios), it turns its self off. WHY!? I dont have any idea. Please help

    Doomlord52,
     
    Check the contact between the CPU and the heatsink / cooling fan.  Is the contact surface of the heatsink bare or does it have the black foil on it?  If it is bare, did you put a light coating of thermal paste (thermal grease) on the contact surfaces of the heatsink and the CPU before installing it?  If there is too much thermal paste, or not enough, the CPU will overheat and automatically shut the system down.  It will sometimes take less than a minute for the shutdown to occur.

    The heatsink came with a "thermal pad" of some sorts, we i have used. The heatsink is in the correct position. I doubt that the CPU is overheating, as i can still touch it easily. It feels slightly above room temp. (about 20c).... Well, i started it up, and for the time it ran, i went into the heat display thing. IT SAYS MY CPU IS AT 87c! That s probably the problem. But i doubt thats right, because withing 30 seconds of turning it off, i can put the CPU in my hand. (it takes about 30 seconds to pull the heatsink off).   *UPDATE!!!!* well, i re-seated my heatsink, and started it up, and it runs at a nice 40c. It seems to be stable,  as it hasnt died yet. :D
