computer freezes with random vertical line pattern

[nytrick]

My computer freezes all the time for no apparent reason.
Every time it does, a different pattern of vertical lines
appears on the screen. Sometimes it is black and blue
thick stripes, other times it is gray, blue and beige
thin lines. It always occurs at a different time in the
middle of a different task so that it doesn't seem to be
connected to any particular program. I'm also running
Norton antivirus and systemworks
