Crazy weird checkerboard squares on my screen
I'm running Tiger 10.4.3 on a dual 2.7 G5.
My computer froze today, with a weird checkerboard pattern on the screen. I had to force a restart by holding down the power button, and when it came back up the squares were still there, but in a different color. Here is what it looks like:

The little green dots flicker, and when I move windows around the red squares multiply, filling up the window
I initially thought this was hardware related, but when the computer is booting at the start the squares are not there (they appear the second the screen goes to blue), and when I boot from the system software DVD, they are not there either. Also, the mouse pointer is on top of the squares.
I performed an archive and install, but the problem persists.
Has anybody ever seen anything like this before? Any ideas?
