Whenever I wake the computer (iMAC G3 graphite running 10.4.6) and attempt to enter my password the computer locks and cannot type in the password. When I unplug the keyboard and plug it back in I am able to type in my password. Now, this does not happen all the time. It has been happening on and off for some time. It started before downloading and installing 10.4.6 so this version is not responsible. Hardware issue? Keyboard issue? Should I buy a new keyboard and see if that fixes the problem? This issue occurs even if I change USB ports. Any ideas?

Have you tried the following?

1. Repair permissions
2. Run disk repair through Single User Mode (Apple-S after the startup chime)
3. Zap the PRAM (hold down Apple-Option-P-R after the startup chime and keep it down for about three chimes before letting go)

BTW, once you're in Single User Mode, you'll have to follow the directions in order to run the disk repair. Just type "/sbin/fsck -yf" and hit Return (no quotes, and notice the space between the "k" and the dash). If you get a message saying that your filesystem was modified, run the command again. Once it says that your volume is OK, then type reboot and hit return to restart the Mac.
