Yes, it is USB. It is the Logitech Trackman Wheel.
Also, after another few system crashes. I took my tower in for a tune up. So to speak. Just brought and connected my system back up today. The mouse problem only happened while playing WoW. I haven't been able to log in to WoW yet. Also the mouse has been replaced.
The original mouse was dropped in standing water or bite the cheese. But the new one is the same model and brand. Just haven't tested it in-game yet.
On a side note, is it safe to surf the web with only Norton internet security, S & D, and Webroot Spy sweeper?
