Hi mswiech and welcome to the forum.
The first thing you have to determine is : Is this a hardware or a software problem (Or both ?).
To check this , you can use a MS-DOS bootable floppy disk drive (At www.bootdisk.com you can find several) with a pre-configured cd-rom driver.
Then boot in the MS-DOS console and try out your cd-rom drive. If all goes correct , the startup sequence will give your cd-rom drive a driveletter ( usually D: ). Pop in a standard cdrom in the tray and Type : D: [Enter] and then type : dir [Enter]. If it shows you a directory (folder) listing, the hardware seems ok.
One thing i would also suggest is to disconnect your cdrom drive from your computer and ask a friend to test the drive in his computer system.
Keep us updated and good luck ,
