Well gents, I've done it now. I opened up my desktop to clean out the crap and it's not working anymore. I'm so damn frustrated I could shoot it. Shut down, unplugged, grounded myself to the case. I took the side cover off the box, carried it out to the garage, and (with distance) blew it out with compressed air. I've done this at least 5 times in the past without incident. I brought it back in, put it all back together, and started to cry. With everything installed, hitting the power button makes the fans spin for half a second then they shut off. I figured I may have knocked something loose, so I went component by component until I was left with 1 stick of RAM, no video card, no power to hard/optical drives. Same thing happens. I then removed the 4-pin power connector to the motherboard and the fans went full speed when turned on. No POST though. I'm guessing the PSU is protecting itself by shutting down immediately when the 4-pin is installed. I've pulled the motherboard out completely to make sure I didn't blow something behind it to ground, nothing. I can't even get it to beep. I also tried resetting the CMOS, nothing. It's an ASUS P4P800 Deluxe with a Pentium 4 2.8 I leaning towards a faulty motherboard, but I'd like to hear suggestions from others.

I've had that happen. The fans spin up, the fans spin down, spin up, spin down, up, down. The first time it happened I figured I'd killed the MB, well actually a TV Tuner card killed it because installing it into a new build sent that one into the same fit. I built a new computer to replace the dead one. When it happened to the new computer before spending more money tried resetting the BIOS/CMOS with the jumper and that worked fine for me. I still need to test the MB I thought I'd killed, as I'd really like to be able to use the AIW TV card I have for that old AGP MB. Resetting the BIOS/CMOS at the MB is free to try and only takes a minute or two. |

I made sure the CPU fan was plugged in, still nothing. It goes full speed when I unplug the 4-pin mobo cable so I know it's working. I've tried resetting the CMOS several times according to the asus manual. I've checked all the connections over and over and can't find a problem. I just can't believe that by me blowing out the case I damaged something. I have a couple other computers around, I'll try swapping the PSU. I think this may be a sign to upgrade... It just sucks because I'm going to have to replace everything. I've got AGP video and a socket 478 mobo. I've been eyeballing the AMD Phenom lately.

They should be having a "budget i7" chipset out soon. It uses a different socket than the regular i7 though. Both those sockets should be here to stay. |

Have you reseated all of the daughtercards on the motherboard?
Removed and reseated all ribbon (gently) and power cables to fan? Reseated power connector from power supply to motherboard? Cursed the darkness? nevermind  Get a new one. HPdirect has a 50% off sale right now.
