CD Drives not being detected.
Sounds like the CDROM drives broke, become disconnected or it's not being read as the boot disk.
Open the case and check the IDE cable (it's the flat one about 2 inches across) is fitted tightly into the drive unit and onto the board.
In the BIOS, set the drives to autodetect, and see if it shows up. If not, it's dead.
Check the BIOS again to ensure it's set to boot from, and put it at the beginning of the list.
Important stuff to save time looking.
Drivers for the CD-Rom are irrelevant for basic operation at this level so don't worry about them.
Or,
Get it couriered to me, and I'll sort it out for you. If it can be fixed without major surgery.
