I wanted to try to boot from the system install disc, but I don't know how to open the drive tray in order to insert the disc.
Doesn't the tray open key work?
You may have suffered a logic or motherboard failure, or perhaps a partial power supply failure.
Be sure all non-essential peripherals are unplugged and try doing a PRAM reset.
I pulled my PCI card and unplugged the second internal hard drive and tried to restart. I still get stuck on the grey screen with the Apple logo. The Mac made hardly any noise. If I recall correctly, it used to make a lot of noise on startup. I didn't think of the power supply, but maybe you are right.
I also tried to zap the PRAM, but the screen stayed black the whole time (more than two minutes) until I released the keys. Could the problem be the battery? I don't think I've changed it in years.
In my original post I said that, after the hard freeze, I restarted my Mac and got to the login screen. I did NOT get to the login. I meant to say that I got to the grey screen with the Apple logo. I don't know if that makes any difference in diagnosing the problem. Thanks in advance for any suggestions.
EDIT: Also, when I tried to zap the PRAM, the system never chimed. As I said, the screen stayed black the whole time and I held the keys for more than two minutes, which is way longer than it should take based on my experience from back in the 1990's. I don't remember having to do it since I switched to Mac o/s X.

UPDATE: I bought a new half AA battery to replace the old one. I still have the same problem. I have the positive terminal facing the front of the Mac. Does anybody remember the proper orientation? I installed it that way because it looked like there was a spring loaded terminal in the back.
If the battery isn't the problem, I can only hope that it's the power supply.
