Zapping the PRAM was a good idea. While the PC monitor is still
attached try setting the screen to rez to 640x480 at the lowest refresh
rate possible. Then shut down completely and swap monitors. If that
doesn't do it you might even try disconnecting the power cord and
pulling out the battery on the motherboard. Wait a few minutes and put
it all back together. Sounds like something on the Performa is
remembering the settings for the PC monitor.
