PC won't Powerdown

A looooooooong tale.

A friend of mine asked me to have a look at his PC as it wasn't shutting down. I tried all of the suggestions in Windows help, but they didn't make any difference. I formatted and reinstalled XP, and shut down the PC a number of times manually (ie Start, Turn off Computer, Turn Off) without a problem. I continued to install various pieces of software such as drivers, firewall, Power DVD and Avast anti-Virus, again manually turning off at various stages. He is a member of AOL and when I installed that there were connection problems, so I tried to shut down manually, but got to the Windows is shutting down screen, where the system hung, after a 'click' inside the tower. I formatted and reinstalled again, it turned off with just XP installed, but again the PC wouldn't shut down, so I disabled the Network adapter, as suggested by XP's help, and the thing shutdown without a hitch every time. 'Great', I thought. I installed Avast Anti-virus, and guess what? The thing wouldn't shut down again even after uninstalling it. As I said I've tried all of the suggestions in XP's help including the ones using MSCONFIG and System Restore. I don't think it's anything to do with Avast as I successfully shut down with it installed earlier on in the day, and I also had this prob with just XP installed (no drivers). Does anybdy think it could be the onboard LAN? I'm currently formatting again and awaiting any help.............................

Cheers Andy

A bit more info after some more 'dabbling' -
Everytime I put a new piece of software on it does the same thing. If I unplug the PC, turn on and reboot and everything's fine, until I put a new program on. It's not the HDD as I've tried it in my PC without a hitch, and I don't think it's the software as I've tried 2 different copies of XP Pro and a copy of XP Home with the same results.

Possibly the motherboard or processor?

To be clear are you talking about

shutdown = whereby the operating system hangs at some stage


powerdown = whereby the OS closes down but the power is still on and the hard drive/hard drives may still be showing power.

At bit of both I think.

The OS hangs at the 'Windows is shuuting down' screen.
The Soft Off button doesn't work at this stage either.
I'm pretty confident that it's not a software prob as I installed the HDD on my PC and didnt have any probs at all.

Technically that is shutdown.

You already have some links. The two i like best are

Given the effort you have gone to it sounds like a Driver problem. if you have got a via chipset on a pci card they are getting a lot of blame at the moment.

I presume you have checked Power Management settings in the BIOS?
