Mouse freezes

Recently I have had a problem every 2 or 3 days where the mouse suddenly
freezes and 2 or 3 seconds later the screen image gets corrupted and shows
lots of coloured horizontal lines.

Recovery is only possible by rebooting but I can access the computer over my
network (read drives, open files etc) so Windows is still running.

What are the likely causes of this?
