well you said that already reinstalled the mouse and drivers and stuff. so go steal one of the plug-n-play mouses from somewhere in your house or get a cheapo one from the shop and test if that one works. if it does its probably your mouse.

otherwise ctrl-alt-delete and make sure theres no processes with weird names that you dont know about. especially temp files. i dont know why a trojan or sometihng would muck around with your mouse.  but better look anyway.

Otherwise i don't know maybe wait for more reply's or get it checked out by someone.
