Everytime I run Bearshare, after about 2 or 3 minutes, I get the blue screen of death, and a message telling me that that there was an error in VXD(01) VMM. My computer is frozen and even CTL-ALT-DEL doesn't reboot it. Sadly, I then tried Limewire and got the exact same problem. Any ideas?

Your going to need to do a system restore, thats assuming you have windows. Go to system tools under accessories, system restore. Go back to a previous date before all these problems happened, go way back. You might want to make some copies of your stuff, pictures, songs and programs you dont have disk to. Good luck
