Hey, very cool, thanks for the thoughtful replies. I do believe I've checked the registry, and wiped out everything before I reinstalled. It's been a while though, and will go over it all again.
I was simply running Windows Media Player when I unplugged the EWS, so I'll try that last. I'm hoping it's a simpler fix than that though, as I'm still sort of crippled when it comes to the whole computer code / software/hardware relationships / OS-related stuff... all that microsoft-connected apps business that's very closely related to the OS is the stuff I just try and avoid. Interesting thought on the software though, I'll try to make that last on the list!
Thank you for the suggestions, and I'll get into it soon's I get a moment here. I'll post again when I've run the gamut and have either a solution or more questions!
