    PC Specs:
    AMD Sempron 2600+
    ASUS KV8-MX Motherboard
    512 MB PC3200 DDR
    80GB WD HDD
    Windows XP Home

    Sometimes the PC will not boot. When I press the power switch the green power light comes on and the amber hard drive light stays on but nothing on the monitor. Once in a while, at random, it will boot and all is fine. You can restart as many times as you want and it will stay on indefinitely, but as soon as it is shut down that's when the boot trouble starts.

    I have tried new RAM, Power Supply, Check Disk, Fixboot, Scanned for viruses & spyware, checked temperature of cpu, changed ide cable, checked BIOS settings, updated XP, defragged the drive, disconnected anything unnecessary, changed power switch, checked motherboard for signs for damage. Nothing seems to work, please help.

    Sounds like you are down to motherboard as you certainly did all I could think of...I am also wondering if the power switch itself could be the problem...what exactly happens when it does not boot? I mean normally I would say psu here first off.

    With the intermittent problem, it would seem that something is beginning to fail.

    IMO - The harddrive, possible floppy or CDROM drive. As well corrupted BIOs.

    I changed the power switch and still the same. When I power up the power supply turns on and all the fans, cpu & case, work but nothing shows on monitor, its black and the hard drive light stays on constantly.

    I have disconnected the floppy & CDROM drive. I also checked the hard drive using Western Digitals Diagnostics Tool and Check Disk everything is ok. I also reloaded the BIOS default settings.

    More possiblities,
    Motherboard grounding out.
    CPU beginning to fail.
    Motherboard beginning to fail (My personal opinon "ASUS" are problem childs, from
    my own experiences).
    Bad cables (They'll fool ya sometimes - been there, done that).

    I understand the frustration, a lot of times its just a little thing that causes a lot of problems.

    Something siad here caught my eye and I notice you have not tried a different video card, and that could easily be the answer also.

    It could be as simple as a problem with the boot.ini file. Use the Recovery Console, run fixbmbr to repair, if no luck run fixboot to rewrite the mbr.

    If no luck I'd try the repair install I linked on my previous post.

    This cannot be a Windows issue it must be hardware related because I installed a new hard drive with xp and I get the same results. It takes many attempts to get the pc to boot. I switch off the power supply and unplug it for 1 to 5 minutes. Then plug it in again and switch in on and press the power button. I may have to do this several times to get it to start. Any way to test the motherboard?
