I've got an iMac G5 that had been working fine until yesterday. Now, when I go to power it on, it starts up, a cd in the drive makes some noice, and the screen freezes on the grey screen with the apple on it. About 5-10 seconds after that, the fans kick on at full speed and nothing else happens.

Does anyone have any ideas?

well, thats the cause of the problem. it must reconize the issue and is failing the hardware scan before booting. try doing this:
apple support said:
On a PowerPC-based Macintosh (but not an Intel-based Macintosh), you may use Open Firmware to eject a CD or DVD disc when normal methods for ejecting it have not succeeded.

To eject a disc with Open Firmware commands, follow these steps:

1. Restart the computer.
2. Immediately after the startup sound, press and hold the key combination Command-Option-O-F.
Note: The Command key has the Apple and (
) icons on it.
3. Release the keys when you see a white screen that says "Welcome to Open Firmware."
4. At the prompt, type: eject cd
5. Press Return, then wait a few seconds. The disc drive should eject any disc that is present, and "ok" appears behind your command when the action is complete.
6. Type: mac-boot
7. Press Return.

Your computer should now start up normally.
if that won't get it out, then its time for you to take your mac to the closest apple authroized repair center so that they can replace the drive, and exstract the disk from the old drive.
