I have an original iMac running on 10.4.11. I am kicked off the internet because it is asking for a Keychain password - I do not have a keychain password.

Question

I have an original iMac running on 10.4.11. Suddenly I could not sign on to my browser, although I was connected to the internet - with 4 bars. I would get signed on and then get kicked off because Safari was requesting a Keychain password. I never used keychain so did not have a password.
Eventually i tried to reload the original software, but am niow unable to get the computer restarted and startup disk is in the machine. I have tried to start by holding down the "C" key, but after the apple comes on it reverts to a "Darwin message"
