[Windows 7 x64 hangs on Shutdown and Reboot]

Hi,

I have a problem with shutting down and rebooting windows 7 on x64.

It takes about 7 minutes and it occures in about 90% of the cases.

Very annoying indeed!

I already read alot about this on the internet, as it's a common problem with W7

Some causes were given:

- M-audio driver had a bug

- Power management on usb ports and firewire

- Nvidia graphic driver

But I failed to fix the problem and I'm kinda desperate at the moment.

I have a clean install of windows 7 and the problem started to occure when installing Nvidia driver.

One fix I used was a .bat command: net stop "nvsvc" (before shutting down)

That didn't work either...

I already traced the shutdown, see the picture.

Can somebody help me? If I need to send more pictures of the shutdown trace, just say so
