Yes it was a fan that came with the processor and had a small amount of heatsink on the bottom.

The fan is spinning

psu is 400watts, cpu intel pentuim d, mem 512, m/b rs400a, gcard 512 ati rad x1300

When i boot the computer i get the m/b name on the screen then it gets to the windows loading and resets but it doesnt reset all the time at the same point some times it wont change screen from the motherboard name at the start, it resets at different points.
