I don't know what your reason was for resetting the BIOS, but you have to choose DEL to enter setup, then correct all the settings. If you have a USB keyboard, you're gonna have to switch over to a PS/2 type. Clearing the BIOS more than likely disabled USB keyboard support.

Yeah, I thought about that. I changed the wireless keyboard and mouse to PS2 versions and it still freezes at the same screen and nothing is excepted.

So, was the computer giving you problems prior to clearing the CMOS?

Apparently something infiltrated my antivirus/firewall and was keeping me from being able to boot into safe mode. As well, when I was able to get to the advanced boot options page, the keyboard suddenly would not work.
I had run the antivirus program in normal mode, then tried to boot into safe mode to run it and it would not work. I then tried to load the XP disc and boot from it, but the system would not allow it. Next I cleared the CMOS by unplugging the computer, and putting a jumper on. Then I removed it, plugged it back in and rebooted the PC. The same message. Then I tried removing the battery and once it was reinstalled it had the same message.

You may be waiting too long to hit Del. I don't understand why you would see a screen stating you were in safe mode unless you were booting to Windows.

Try continuously tapping Del as soon as you start teh computer.

I have tried that several times prior to and since I began this thread. I just tried it again and still the same answer.
The computer is sticking on the second black screen with white lettering that describes the hardware attached, CPU, motherboard and RAM.
I am beginning to wonder if the keyboard is not being seen.

As I suspected, the connection of the PS2 keyboard or the adjoining PS2 connection on the motherboard for it, was not connecting completely. I worked with it and like magic, I got it to see the keyboard and thus fixed the problem. Now the system is up and running and my original plan of action fixed the original problem.
Thanks for the help.
