My CPU appears to work when plugged in to an older board I have lying around, and my board appears to work only when my CPU is not installed on it. The CPU fan will do about 1 full revolution, then stop. The machine is getting power; all my board's LEDs are lit. My PSU is 400W and the board is also quite new. I have tried stripping the board down, and none of my other components are causing the problem. Specs are as follows:
Intel Pentium 4 @ 3.2ghz (Prescott)
Aopen i865Gm-I (PhoenixBIOS)
