Try the "LimeShop" uninstaller in the Control Panel - Add/Remove Programs. That should take out the LimeWire trash, but other prog's crap will still be there, which can wreak havoc as well.

In you have Win98/ME/XP, try going Start->Run and entering "msconfig" (without quotes). You may want to pay close attention to the startup tab. Many problems can be solved here.

And an hour to dl a song?!? Was probly a slow******* source, but whose to say for sure?
