My Sony Viao FXA48 laptop keeps freezing. Only rebooting unfreezes it. It locks up when I'm moving the pointer on a microsoft optical mouse (which has worked for a long time). I've uninstalled the mouse driver and it didn't help. What to try now. Maybe it has nothing to do with the mouse. If I unplug the mouse, I have yet to get the pc to freeze, but I HATE the mouse pad. Thanks.
