I am building a computer from all new parts. I have everything needed for powering up but when I push the power on button, my cpu loads with power for only 1 to 2 secs and then turns right back off. I have a roommate with the exact same board (intel D865perl) and we switched cpus. When his cpu is on my board it powers up fine and when my cpu is on his board is powers up fine. We have checked other connections, shorts, parts but nothing is wrong. So that leaves me puzzled because we have the same board, same cpu, my cpu works on his board, his cpu works on my board, but my cpu won't work on my board. Is there anything I'm missing on why my cpu doesn't load on my board?
