What speed is your CPU, this does sound a bit like a overheat prob.
Is the heatsink bonded to the CPU or does it use a non-bonding thermal compound, does it have a thermal compound. I had a prob like this with my Athlon 1GHz, I reset the Bios, and got it to boot I took it into the Bios, so I then slowed the CPU Clock to 300Mhz, I was then able to get it to boot properly and install Windows. That was all I needed, I was then able to get online and order some new thermal compound (Arctic Silver, the best stuff on the planet) put that on and cranked up the clock and all has been fine.
The prob with mine was that the Heatsink had some pink thermal goop on the base covered by some waxed paper, I removed the Waxed paper as it was (correctly) preventing proper heat transfer. This resulted in a small gap between the heatsink and processor and casued crashes. The CPU had always run hot (50-60 C.
The old themal compound had molded around the processor shape, but it didnt properly match or contact without the paper.
Once I removed the old compound and replaced with Arctic Silver 3, it was fine, the normal operating temp is 47 C full load (its always at full load as I am running the United Devices Cancer thing). No load is 35 C.
Would it be possible for you to post some pictures of the motherboard, CPU, heatsink, and Power supply, individual and all together if possible.
