7 won't turn off - Stops at "Shutting down"-page

Hi experts

I have two problems that are driving me insane.

1) I can't install a fully working driver for my Atheros. I have tried all drivers mentioned in the "Windows 7 drivers"-forum, but none of those fully working (Still blinking light). The last option I could see working is deleting that "TrustedInstaller"-protected driver, but I have no clue of how to do that.

2) Since installing Windows 7 on my brand new AAO 160gb HDD 1,5gb RAM, installed as only OS, my PC hasn't been able to turn off. I get stuck at either "Logging off" or "Shutting down" - And that's it! It's always to be turned off by pressing down the Power-button, but that isn't the healthiest solution to my little netbook..

SO - What can I do? Please notice that this problem has excisted since install - It can't be any software installed since that's causing the problem. Now, I have seen a difference when uninstalling the driver for the Atheros-card (PC freezes at "Shutting down" instead of "Logging off", but problem still isn't resolved. Please don't give me the "Google-it"-answer, as I have done this countless of times..

Cheers
