computer won't turn off

hi I've got a machine with an intel 810 chipset, pcchips motherboard, and 466 processor running win2000prof and it doesnot turn off.

What happens is that you shutdown and it goes to the now safe to turn off your computer screen then just stops without turning itself off.

That I wouln't mind but when you hit the power switch on the case it does nothing the only way to turn it off is to switch it off at the wall.

After switching it off on the wall when you turn the wall switch back on it behaves as normal (that is it doesn't start) and when you want to start it again just hit the case power button and it starts, but of course wont fully turn off.
Any ideas? Motherboard; Bios; (Powersupply ok newish)

 

Sounds like a wrong BIOS setting in Power Management. What is when you keep your finger longer then 4 sec. on the power button to switch off?

 

checked
When I keep my finger on the button longer than 4seconds it powers down but then reboots kinda like when you push the reset.

is this controlled in the bios?

 

That has to do with 'Power Loss Restart' probably. You can find out in your motherboard manual - bios setup.

 

I have the same problem w/ same board. It powered off fine using Win 98 but after loading XP Pro it doesn't power off at shutdowm... I checked the BIOs and don't see anything that may resolve the problem.

 

Maybe a BIOS upgrade is needed? Checked the manufacturer's site?
