    I've got a PC that won't boot. No OS, no POST, nothing except running fans. I have an identical PC here that boots fine, and all jumper settings are identical. Any thoughts? Thanks ahead of time :)

    I would start by removing everything that you dont need, things like, Sound card, network card, Leave 1 stick of ram in there, unhook the HDD. etc etc

    If it boots up then slowly start adding each part 1 by 1 untill it does not boot and that will be your problem.

    Now if it does not boot then try some things like,
    - Try other ram stick and remove one thats currently in there.
    - Try different video card
    - Try different monitor just to make sure
    etc

    If that still does not work, try another powersupply.

    Post back with results.

    Ciao

    Thanks for your help! Tried all of the above, but unfortunatly it had no effect. In addition, we replaced the CMOS battery. The only two other things I can think of are motherboard or CPU problems. Any other thoughts before I tear out the motherboard?

    Try removing all the ram see if anything happens, any beeps and so on.

    Also reset the cmos just to try, remove the cmos battery for about 5-10min to reset.

    It would help us if you would include some system specs, make and model of system or Motherboard, Processor, Ram, Video, HDD's Optical drives, added cards such as Network cards, etc and OS. Also is thisw a new build or has it run before? Was it running before then wouldnt run when you started it again?

    IBM 8305 51U, P4.... unknown OS. We don't know when the last time it worked was. It was in storage for months.

    Is this an IBM prebuilt system? It sounds as though it might be. What you describe sounds a lot like a bad power supply. Just because a few fans spin and a few lights light up does not mean that the power supply is capable of operating the system. According to a search of the IBM site this came with a 185W Power Supply and onboard video, a 40gB hdd possibly a CDRW and Floppy drive.

    without a decription of any system beeps it sounds like cpu and/or graphics card, if you have an identical system there as you said then try swapping cpu's between and see if the problem follows the cpu to the other system. do the same with graphics.
