Computer refuses to accept that it has CD drives

[Guest BDC]

Okay, my computer flat out refuses to believe it has any CD drives, except in Device Manager where it will tell me this message:

 

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

 

I have one old CDRW, one CD ROM and one Toshiba DVD Rom, all of which get this message. Yes, I've uninstalled, yes I've tried driver updates. Any ideas?
