Won't take keyboard input

This machine is the 2 Ghz DP version, 2005.

It will chime and boot to the internal HD.

I lost the password so can't login.

I then try with the DVD install to reset the password.

It will not take any keyboard input combination to reset NVRAM, boot off DVD---nothing.

The keyboard works because when I tried some password input it prints on screen.

I took the HD out, put it back in and on an SATA channel it did not like. It did not boot.

I changed it and it booted but this time without anything on screen...it does not seem to boot completely.

I cleaned the tip of the video card. No luck.

Any help will be appreciated.

Thanks

Update

I must also mention that I've removed RAM, battery, etc, to see if it's locked with firmware that's preventing the keyboard input at boot, but no luck. I think that's the real problem here....not responding to keyboard input during boot.

See if the "Option" key will work when booting with the DVD inserted. If so just select the DVD disk. It also sounds like you may not have connected the SATA data cable completely or have a bad cable.

I have an Intel MacPro that got a lightning hit and I can not access any of the native USB ports. I installed a Sonnet Alegro USB PCI card (mine was PCI-E) and all works well now. Her's the card you may need: http://www.sonnettech.com/product/allegr...
