AK75 Motherboard won't boot

    I have an AOpen AK75 motherboard with AMD 1800 cpu. I am running
    Windows XP Pro. My computer randomly won't boot up at all, the monitor
    stays in sleep mode. I can't reset or even turn the power off. The
    only way to get the system to boot is to remove the power chord from
    the back, and try again. This can sometimes take 4 or 5 tries.

    I would like to fix this because I can't really afford a new mother
    board. Has anyone seen this before?

    The motherboard was already replaced once (for this same problem)
    while the PC was still under warrantee but that has now expired. I see
    positive feedback on this board, but have yet to be impressed.

    Any help or suggestions would be greatly appreciated.

    Hello Heather,

    Some possible causes in order of probability:
    1. Mains cord connector fits loosly in power supply socket at the back.
    Try another mains cord.
    2. Power supply connector not properly seated into mainboard connector.
    There should be no gap between male and female power connectors.
    3. Reset button or its wires shorted.
    Try power up with reset unplugged.
    4. Power button or its wires shorted.
    Try power up by 'plug - unplug' power BUTTON connector to mainboard.
    5. Bad power supply
    Try a replacement.

    Tell us what you found.

    Hope this helps,

    I have this EXACT same problem. It drives me nuts!

    One week it will be fine then another it wont boot until I pull the power cord from out the back a few times. I think it may be the motherboard (which i only got 6 months ago). I have re-installed windows, new memory, new processor. new HDD. What else do i have to buy!

    It memory checks in BIOS but then nothing, it dosn't load/check the IDE drives, it just goes to a never-ending blank screen and monitor loses the signal.

    Any Ideas?
