Old CD rom not accessible

My friend asked me to help him with his old olivetti PC.

The CD Rom will not work - it is always not accessible.

However a D: icon always appears in my computer and SONY CD-ROM CDU 311 appears in device manager, which claims it is working properly.

I can right click over the D: icon and eject the drive but that is the only operation i can apply.

When doing a step by step confimation boot this message appears.

"The following file is missing or corupted: C:\CDROM\GSCDROM.SYS.
There is an error in your config.sys file on line 7"

I have removed the drive via device manager.

Add new hardware wizard fails to find it but it is always there on reboot.

The CD rom has been not working for a few months.

My friend has kids about the house who may or may not have gone around messing with system files.

Any Suggestions?

Edited text of question.
If he only uses th cd rom in windows you can delete the line in the config sys. Windows should then recognize the cd rom and uses windows drivers.
Comment the references to it in autoexec.bat and config.sys.  It could be confusing Windows.  Windows doesn't need those drivers.  They are for real mode only.  Windows has its own protected mode drivers for the cdrom. New hardware wizard will never find it.  However, when you remove it from device manager, hit refresh and see what happens.  Also, make sure there are no yellow !'s anywhere in device manager (especially on the ide controllers).  If this fails (the driver commenting), then I'd have to say that the optical reader in the drive is misaligned or dirty, if not outright busted.  Get a cleaning cd in there if you can get it to run.

sorgie and biard both have good suggestions and I would just like to add this.
This could be a hardware issue, the best way to check that is to boot from a floppy which loads up the CD rom drivers, then try the drive dos. If it fails to brows a CD it's probably dirty or dead.
The cdrom drive is dead, mine just did the same thing and the tech support said that it is gone.

You need to get a new drive.
See the 'CD GOD webpage', at:

and download the software to create a new version of the 'GSCDROM.SYS' (GoldStar) device-driver.

Put this file into the '\CDROM' directory on your computer, reboot, and see if the error-message vanishes.
Carefully put a cd in, aligning something on the top with a point on the tray.  Access the drive ( you'll get an error message).  Open the tray and see if the cd has moved at all.  If it hasn't, the drive is probably toast.  How old is the drive anyway?
