Faulty board.........

[arbitor]

really? the rest of the functions on the board work fine..

There is no1 else who has had this problem?

You're definitely shutting down and not hibernating or anything? Maybe you have one of those PSUs that runs the fans for a bit after the machine is shut down to cool things? (that said, 15 mins would be a loooooooong time!)

[arbitor]

no im deffo shutting down, and its been half an hour now still on..

strange thing is i have another machine here that is one of our work ones it does the same..

doing my head in i cannot afford this to be a faulty board

[markymicro]

Any other faults or just the fan thing?

[Splash]

[arbitor]

you're sure you have the switch headers on right?

i've had a problem like that before..asrock though..they're cheap for a reason.

[arbitor]

at the moment im bypassing the switch headers and just using as manual switch and shutting dow normally..

i knwo they are cheap but i havent had a problem like this with them .


update, i have two of these i just tryed it with a brand new one and the same thing happened!!

rules the mobo out tbh must be something else..

[staffsMike]

Well if its not the motherboard its the psu..or voodoo.

Has the psu you're using worked in combination with that motherboard before?

I'd try it on the headers though just to be sure.

PSU just keeping them running until it's happy things are cool?

How long have you left it for?

//edit: nevermind, just fully read your first post.. doubt it's that then.

What is the PSU?

And why's it urgent? :|

[arbitor]

as its a customes machine that im installing into thier office network today hopefully.

i will try a different PSU they are just generic ones that we get in. they are normally fine. il try a diff PSU .

voodoo whats that?

i wll try again with the headers and different PSU

[staffsMike]

voodoo.. is witch craft lol

[arbitor]

agony hate pcs dire bits of equipment

I think it was mentioned a couple of posts ago but I don't suppose you can double check the headers on the board are connected the right way around can you? Also disable any form of power management in the BIOS and see what that does.
