Computer won't fully turn off

[Peter Grainger]

Hi,
If anyone could help me i'd be very grateful.  I have  an AMD Athlon K7VT2.  One day I was testing another persons computer and removed the power suppy and then reinstalled it in my computer.  Ever since then the computer will shutdown but I cannot get it to turn off completely, even using the power button on the front, it has to be turned off at the back.  This doesn't bother me, but when I turn the computer on, XP always crashes at least once.  Any advice on this would help me alot.
Thanks,
Pete

Have you checked the CMOS power settings?

[THEshortMONK]

yeah, I reset all the settings to default and checked that the power settings weren't on 'turn off to standly' or anything

[Raptor]

Did you properly connect all the power cables?

[THEshortMONK]

Yeah, and I tryed another power supply in case that supply, cable or connector was faulty and the exact same thing happened.  I also updated the bios and all the drivers for that motherboard.

You've missed something...m'board connector not locked or obscure BIOS setting, or some wire is loose.

you say winxp crashes at least once what error /stop messages?

[THEshortMONK]

There are no error messages.  The computer just suddenly stops working, usually when XP has just started and sometimes when it is loading up.  The only option is to turn it off at the back and start again.
