floppy drive not working at all under windows, Cd rom only music cd's

All of a sudden the 3 1/2 drive is not working under windows, if I start the cpu with a boot floppy drive it will work in only dos mode. When In windows on windows exporer it gives me the "no a valid funtion, or incorrect funtion" same thing with the cd rom, but if I put a music cd it works fine. I have windows 2000 pro, I want to know how to reinstall the registry, or what keys on the registry should I edit to have this floppy and cd rom working again. When I go to dos mode under windows it doesn't work either. I unintall the floppy and reintalled it but nothing. Any ideas or suggestions?

Try reinstalling the operating system, or move to a newer one.

1. Try Getting Into CMOS/BIOS and Check Whether The Following Are Correctly Entered.

a. 3.1/2 Floppy With 1.44 MB FDD
b. FDD Controller: Enabled
c. Boot Up Floppy Seek: Yes
d. Report No FDD For Win 95: No

2. Try TO check Whether The Power Cable And The FDD Cable Is Properly Connected. Check For Loose Cables Or Cut/Bent Cables. If Need be, go for a replacement.

3. Restart The Machine, Windows Should Detect The New Drive.
