Re: help with volume control
Sounds like you have some form of corruption - i use AVG and Spybot 8.0, both are normally quite good. Try updating the definitions on them both and run again. If that doesnt work i would try to download some free anti-spyware and run that. If that doesnt work - you may be facing a complete reinstall of Windows, so make sure everything is backed up.
I'd go through the list of installed programs aswell, remove anything you dont need or have recently downloaded and installed. Run Disc cleanup and then defrag afterwords. Check what applications are running on startup (bottom right of screen, next to clock - if you have to many icons here, you have to many unnessacary programs running auto on startup.
