All power cables are connected to the motherboard? 2x12 and 2x2 connectors? Is there a cmos jumper on the motherboard maybe it's set to factory ship vs. normal? What about your psu? Can you try the motherboard with a different psu? LEDs require very, very little voltage to light. You need fans spining or something to make sure everything is working. Hard to image something wrong with motherboard when you have an Intel cpu and 2 Intel motherboards. Intel makes some tough boards and cpus. No offense but I have to go with a problem in your assembly skill, your psu or memory first. Try again then trying talking to Intel Help link. IIRC, they're pretty good or send an email through their website. The website will probably send stock email reply but replying to that email might get you more help. And Intel honors it's guarantee, unless someone has clearly mangled the cpu or motherboard.

It does stay on. there is a different light on the POST diag board that blinks on for a second. I've tried several different power supplies and none make any difference. I've tried it with just one stick of ram and swithed which ram stick that's in. I've got no drives plugged in and the sound and video are on the motherboard. I've even cleard the CMOS and tried to reboot then. I still get nothing. Any other ideas?

You've tried several power supplies, and all you can manage is a twitch. I'd try another motherboard. Paul

I'd try another motherboard. Cant be that, he's already tried another motherboard. Gotta be that it doesnt like that ram since he's swapped everything else or the bios doesnt support that cpu, unlikely. |
