Here is how to reset the open firmware password. This is an intel mac so not sure if open firmware applies but it's still worth a shot :)
After removing or adding additional RAM turn on the computer and immediately reset the PRAM by holding Command, Option, P, R. Press the keys until you've heard two additional startup chimes. (3 total)
The open firmware password should be disabled. Shut down the computer and return it to it's original RAM configuration.

This sounds like a software issue. Can you log onto the computer? Does it boot up? To what screen? What system are you running?

If you need to get around the firmware password you can change the ram configuration to do that.

Reseting the PRAM is a much easier way to clear out firmware passwords, hold command+option+p+r on the keyboard right after you turn on, and keep holding them until it has chimed 3 times
