Specs first though:
Intel Core 2 Duo E8400(3.0GHz)
2GB (2x1GB) DDR2 800
500GB SATA-II 3.0Gb/s 16MB Cache 7200RPM HDD

Chipset: nForce 650i SLI Chipset
Motherboard Name: ASUS P5N-E SLI
PSU: Ultra LS 600 Lifetime series(600w) also tried a Antec earthwatts 650w
Things I have tried:
1). Removed both sticks of RAM trying them one at a time.
2). Removing the HD(from PSU and SATA).
3). Removing both video cards.
4). Removed the heatsink and reinstalled.
5). Check the CPU chip for damage.
6). Checked all cables to make sure they were secure.
7). Cleared CMOS.
8). Tried a different PSU.
9). Tried just the motherboard being supplied power.
10). Tried a different outlet.
Things I have not yet tried:
1). Replacing the motherboard.
2). Reseating the motherboard.
Basically I haven't performed these steps yet because I wanted to exhaust all other options first. I will list more things as I remember them and or perform them by the suggestions posted here.
