CD ROM won't start in Windows 7, Dell Inspiron 530S. It shows up in Device Manager, but not under Computer. Can't read DVD.

Can you suggest how to enable this please?

In Device Manager, does the device entry show any errors? – K.A Jan 15 '13 at 2:44
If it's really a CD-ROM, then you won't be able to read DVDs. Have you tried booting from it? – Ƭᴇcʜιᴇ007 Jan 15 '13 at 2:49

I've had this problem many times on different computer brands. It's usually nothing more than a simple registry fix.

Click Start
Type regedit
regedit will appear at the top of of the menu. Right that, and click Run as administrator.

In the navigation pane, go to the subkey "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}"

In the right pane, there are two keys named UpperFilters and LowerFilters. Delete them. Don't delete or modify anything else in that menu.

Close the registry editor, and restart the computer. Your disk drive should now be working as expected.
