    Hi
    I fitted my brand new asus A7N8X Deluxe Rev2.0 board today
    along with my brand new 80 gig serial seagates

    the problem is when i switch my pc on it powers up fine for about 10 seconds then switchs itself off!!! :(

    I have checked the "helpful" staus leds and they are all fine i just dont know whats wrong

    can anyone please help ?

    (it doesnot initialise the monitor or post)

    strip the board back to board, cpu, heatsink (making sure its got the yellow wire plugged into a fan header to show fan speed as this can prevent a P.O.S.T.) and ram, try a basic power up at that, then add the video card back in, 1 by 1 until you find a bad or loose part. take your audigy 2 out and use the onboard sound as this has voice on POST to tell you whats wrong. good luck :)

    Right I just tried what gonzo suggested....... still no joy its the same even without the gfx card in powers up for a few seconds then switches itself off. I did not have an rpm monitoring fan in the cpu connector but i just changed that so that should not be a problem i also disconnected all my ide and sata devices and the floppy from the board still no joy i have also tried it set to 200fsb just to check and no joy :(

    failing that take the cpu out as well and try a POST with a bare board, im sure that asus woman starts shouting no cpu on a bare board, have you reset the bios as well ?

    have a play with the memory, hopefully 1 will behave enough to allow the cpu back in etc.

    It could be your power supply. An open short in a device or the motherboard would cause an immediate PSU shutdown to keep from frying your components.

    right i just tried a bit of investigation using the post reporter, failed memory test seemed to be there alot but after shuffling the ram around i manged to stop it the problem is it jus t now switches off again, actually the only time it did not switch off again was when i took the cpu out and it just kept saying no cpu although it did not shut off. After putting it back in again no messages it just shuts itself off

    i have an old athlon thunderbird 900 is that worth a try of course i would have to switch the fsb down to 200 for that but i looked on the asus website and it says it supports them. the athlon xp was weird in my abit board i had to set it the xp2200+ for it to work correctly
