Phil: If this were to happen to me again....I would shut down the system, wait for it to cool down and then start it up again.
Don't restart: Turn it off & wait five minutes. Start it up & see how the video looks. Then i would start the computer up off a CD....either the system CD that came with it as Install OS or any utility CD with a system on it. How does the video look ??? Do a CLEAN install of the System and start up again. If the video returns to normal running off a fresh clean install restart off a CD and either toss the CLEAN install or start moving preferences over to it. When you restart video should be OK. This has happened to me from time to time, a few weeks ago, after a MAJOR upgrade (800 Mhz G4 card & sonnet ATA card and OrangeLink USB/FW card) where all of the possible resolutions disappear in the Monitors and Sound control panel, except for 640 X 480. Then I would check to make sure that my hard drives were correctly ordered and described in the System Profiler, and properly terminated, if SCSI.
