    So this afternoon on the net and it suddenly went off, and it was the cable at the back of the pc which had come out a bit(the clip has broken) so pushed it back in and the pc went off, so tryed turning back on again and all that happend was the cpu fan started and heard the hdd spin but there was no power light on or hdd led, so put in another psu, cleared cmos, tryed different ram, still doing excactly the same. then put original psu and ram back in and cleared cmos but removed battery and put back, then it started fine no problems, and was on about an hour or so, turned off to watch top gear and after that went to turn it back on and now doing the same again wont switch on no power light just cpu fan spinning.
    repeated last steps but still nothing.
    Any ideas please :confused:
    Spec:
    cpu: e1200
    board: cheap biostar
    graphics: onboard
    ram: corsair value 1gig

    try to unplug the unnecessary device (Fans, extra HDD etc etc) do a Clear Cmos if you have some overclock.

    No overclock, all thats pluged in is primary hdd, dvd-rom, and case fan which plugs straight into molex connection but left that unpluged at the moment. thats all thats in the case.

    It doesn't have a speaker built on board, so pluged in a spare speaker onto the headers, but no beeps what so ever.
    Just taken ram out and still doing the same and with no beep.
    All that happens is i push power button, cpu fan spins, hdd spins, and thats it, it will do that untill i turn it off, but i have to turn it off with switch on back of psu, wont turn off if i hold onto power button.

    Iv'e just had a look now but i cant see anything like that. or somthing unusual. last night i took cmos battery out, moved the cmos jumper to clear and unpluged from mains over night to see if that made a differance but to no avail. tomorrow im going to take it out of case and and test/change everything i can to see if i can narrow down the problem.

    it look like a dead board to me, but I hope I'm wrong. If really it's 'out of service' well i'm sure you'll find another one here for an unexpensive price or even free (sometime, the bittekers are generous)

    It was a bloody screw that had got stuck behind the board :duh:, dont know how though as it was the top left hand corner screw that was missing so iv just taken board out to have a look and there it was, and now its working perfectly.
    but many thanks to blackswordman for the replys. :thumb: :clap:
