Very strange power problem

[jimmynaetroots]

Hi guys,

one of my colleagues asked me to take a look at his PC tonight and I am completely stumped. It is based on an ABIT AN8 Ultra Mobo and the problem is this:

When you do a shutdown, the PC shuts down as normal and all the power goes off - however, it then after anything from 2 to 10 seconds makes clicking noises, and powers itself up again... I have NEVER seen anything like this before and google is no help - anyone any idea what the problem could be??

Thanks

G.

Joe42,

Thanks for the reply. I have been through the BIOS and disabled all the things that could boot up the PC with no success. I opened it up and the clicking seems to be coming from the hard drives. It is definitely powering right off, everything goes completely silent, and after anything from a few seconds to several, the clicks start. Usually there is one click and it powers on, sometimes there are 5 or 6 clicks. There are 2 drives so I will try disabling one then the other and see if it makes any difference.

Wsa thinking it was the mobo myself but thought I would ask on here before I recommend him to shell out for a new mobo!!
