I can sympatihize with you Kawa. I'm using Vista as well (business tho). A few hours after I posted that backup was a good idea I went to install some new drivers to get my ps3 controller to work on my laptop and I got a virus and it wouldn't let me load my network or sound drivers. I restarted it and searched google on another computer for related fixes and found out that there was an added value for both my network and sound drivers that shouldn't have been there. I deleted them and they both work now and running a scan to try to get rid of the virus.
