I scanned the bases for the best thread for my reply.......
Recently I started having problems with my rollerball mouse so I changed to a laser mouse..... That one worked good for a couple weeks and then started shorting out and when it did,my whole computer locked up.... At first I didnt realise what was doing it but I figured its probably the mouse.....
I took my rollarball mouse apart and cleaned inside. BOY WAS IT A ME$$ IN THERE!!!
I put it back on and thankfully its working fine
