CD drive? Both are possibilities. Otherwise, is the hard drive properly
detected in the system BIOS?

no floppy!

Then troubleshoot this way, making only one change at a time and testing
after each change:

1. See if the hard drive is being seen in the BIOS. If it is not then
2. Swap out the ribbon cable going to the motherboard with a
known-working one. Reseat the power supply connector going to the
drive.
3. If #2 doesn't work, attach the drive to a different IDE connector on
the motherboard (assuming IDE). If the drive appears, you know the
first IDE connector on the motherboard doesn't work and you need a new
motherboard.
4. If #3 doesn't work, attach the drive in another, working computer. Is
the drive seen there? If not, the connector on the drive is broken and
the drive will need to be replaced.
5. If the drive is seen in the BIOS but no operating system is found,
test the drive with a diagnostic utility from the drive mftr.'s
website. You will make a bootable cd or floppy with the file you
download. Boot with it and do a thorough test. If there are any
failures, replace the drive.
6. If the drive is seen in the BIOS and tests healthy, then something
has happened to the operating system that was installed on it. What
changed between the time things worked and the time they didn't?

Start with that and let us know if you need more help.
