will a mobo go into the bios with a proc?

[memo]

I have a dfi nforce4 ultra SLI and its not booting up right now with 4 LEDs in the left hand side, which means "System start up" according to the manual. I think its the proc that could be a problem, but i dont have another 939 to test it with. so i was going to try just booting up the system without the cpu, just ram and a vid card, is this a good idea? will it actually do anything?

It won't work, the motherboard can't do anything on it's own, the CPU is required to boot and get in to bios. What makes you suspect it's the CPU? Have you tried with the bare miniumums(cpu/heatsink and fan, 1 stick of ram, video card). Disconnect everything else, hard drives, cd/dvd drives, any other PCI cards etc.

Is this a new build, or was this a working PC, that suddenly stopped working?

well its was a working PC that stopped. i've got just the basics in CPU/ RAM/ Vid Card and its not booting up. i put the ram and vid card in another machine and they worked fine. so i went to get a new mobo, and its not booting up at all

Have you tried another power supply?

yes i had a spare lying around. all the fans spin up, the chipset and heatsink fan. i just wish i had another mobo or proc for testing 🙁

Have you tried re-seating everything?

yeap i tried reseating everything. i give up on this thing, i had to return the mobo so ill just wait to see if my RMA on the original board comes through, thanks for the help stev
