Allrighty, I am having a rather terrible issue, and i cant seem to find a fix anywhere so im actually posting my own topic (gasp)

I have a Asus P4C800 Deluxe mobo, with a 3.2 pentium 4 prossessor, the prossesor brand new, as is the mobo come to think of it, and nothing else is really important. Oh, and I have 2 PSU's right now, switching out does not solve the problem. Also, i tested the PSUs with a paper clip, seem to work fine, so i doubt its them. anyway, sorry, acutal problem.

I plug everything in, that being, the motherboard, power supply, speaker and power jumper, CPU and heatsink, and then, a hard drive or somthing. and thats it, outside the box, just on my matress. I flip the back, the mobo lead comes on, and i hit the power. The stupid blue power suply light flickers once, and all the fans jump just a little bit, then nothing. Mobo led is still on. I hit the power button agian, nothing. I have to turn off the back switch and then back on if i want it to even flash on for a second. The odd thing is, if i take off the 4 pin power suply to the mobo, you know the one by the heatsink, the fans will actually totally come on for a minute, as if its started.

Im really in a desprate situation, i supose my mobo crapped out on me and i need to get it replaced but if anyone has any ideas at all?

*yes, im aware of the earlyier thread

Yea I would also think bad board because when you disconnect the 12v 4 pin it decides to power on and you certainly have done all the right things like the out of case test.

Make sure the 20 pin connection is seated good.
Make sure the cpu fan is connected to the correct header on the mobo
Check jumper settings especially the clear cmos jumper is on pins 1&2
Check the + and - of the case speaker is hooked up correct
You mentioned a "hard drive or something" disconnect all drives and unessasary cards and see what happens.

I assume you are getting no beeps right?

With a case speaker connected remove the ram and power on to try and force a beep if it beeps then good mobo but bad cpu would be my guess. You could also do this with the video card. A weak beep also would indicate bad cpu.

Just some ideas to try I hope it helps somewhat
