i just changed my p4 2.6 cpu with a celeron 2.8 cpu, same socket and everything. the computer is a dell 4600. the problem i am having is it will post and go as far as showing the xp logo with the flashing green lights, but after the green lights blink a few times my screen goes black and then my monitor light goes yellow. is my dell motherboard conflicting with the celeron cpu? ive tried everything i know but no good, any ideas?

im curious as to why you downgraded to a celeron? was that a 2.6 c processor?

broke a pin on p4, celeron was all i could afford
