P4x400 won't boot

I also have the same issue though I previously had this board up and running with a 1.8 p4 borrowed from another machine for testing purposes.
Fast forward years later I am again building the same board and having no recollection of the specs I found one review that claimed it supported up to 3.06 p4's. I bought a 2.8 and high density ram that according to the sellers site worked in this motherboard. I get no video though all fans run, cd drives appear to boot and hard drive sounds like it normally does during a boot cycle. I believe I agree with the p4 2.4 max comment and am looking forward to, uh, downgrading to one. I would like to know the Celeron range as I may move into one of those as I believe they came out after the p4. How do they compare in mflops? Anyone?
