    1) doublecheck all connections....especially the cpu fan and front panel.

    2) remove everything except one stick of ram, video card, cpu/heatsink, powersupply.


    3) check cmos jumper to make sure its not in the "clear cmos" position.

    4) boot and see if it posts.


    if it does, add one component at a time until you find the problem.

    if it doesnt, then if it beeps, its probably video card or memory(beep code will tell you which). if it doesnt, its probably motherboard, powersupply or processor.


    trial and error from there swapping parts with known good until you replace defective component.

    Can you try to get it to boot with just the floppy.....disconnect the hard drive, cdrom.......are you sure you put the jumper pin for the cmos on the correct pins?

    I suggest you remove the MB from the chassis, since you may have a short. Power it up with only the MB, memory, and obviously CPU and video board. Connect a keyboard and the P/S and see if you can enter the BIOS. You need to get that working before you even worry about the other equipment. Once you get that working, add the floppy and make sure you can boot from it.

    When I have a problem MB, I normally build the whole system laying on the bench and get it playing, then put it into the chassis. If it dies in the process, I know it's something to do with the fit of the standoffs, or other such issue.
