Sometimes this can be caused by a usb connection try starting without any connected. Try disconnecting the supply cables and reseating them again. If this does not sort it try disconnecting the power cable from each component [hard drive, floppy, cd/dvd etc.,]in turn to see which one is causing the problem.

Hi howard thanks for your response,
i tried the above in the order that you have said,
still the same still wont boot up. The only time it did was when i reseated the cable onto the motherboard, then it started after that but that is the same as unplugging i guess,
any other suggestions please.
Many Thanks again.

Shut down
Switch off at the mains socket but leave the plug in.
Presss and hold the power button for 30 seconds.
(disharges all Mobo capacitors)
Switch the socket bak on and retry booting the PC.

Thanks fruit bat.
If i switch off at the socket it will boot up when i switch the socket back on, there is a green led light on the mobo when this goes out it will start up everytime. Its only when i power xp down and leave it on standby that it wont reboot(led light stays on).
thanks again.

Start your own thread, DO NOT hijack someones elses.

You will then recieve e-mails to let you know if someone has posted a reply.

Strip t bare essentials - just cpu graphics card - one stick of memory and see if it boots as far as an error message about Hdds missing.
