System disk invalid, replace disk and press any key.

This could be as simple as a floppy left in the drive. If it's not a "boot disk", meaning it was formatted specifically to be able to start the computer, then you will get the message quoted above.

If there is no floppy issue, then it could be that the hard disk's operating system (DOS, Windows NT, etc.) was corrupted.

One other thing to check is the "boot order" in the BIOS setup (keep track of any changes you make--incorrect changes to BIOS settings can cause even more problems).

For example, if the BIOS is set to first boot at "A" drive (floppy) then "B" drive (floppy) and then "C" drive (hard drive) you can change it so that "C" drive is listed first. Thus, if there's a problem with the floppy drive, the computer won't get bogged down trying to boot from it.

Also, you might want to try a boot disk to just get into a DOS prompt, and try to access C: drive.

I can try to help you along with this, though these things can get messy...

Almost forgot--you can try finding one of the keyboards that has this:
