PC No Longer Recognizes Removable Drives

I think I meant to say CD drives. I haven't downloaded anything new accept a Pop-Up blocker and an Anti-Spyware program--both from here. My PC doesn't recognize the existence of my CD drives anymore. When I click on the Troubleshooter, I get this message: "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)" Is it possible that either one of the new programs could have deleted something necessary for these to run? How can this be fixed? I don't think I have the original disk that came with my CD-R drive, and the other one came with the computer when I got it 4 years ago, and it was 4 years old then. Thanks in advance!

 

Do you have internet connection?
Update the driver by clicking Update Driver on the Drivers tab. This starts the Hardware Update wizard.

 

Check the sig.

Windows doesnt use third party drivers for basic CD/DVD control.

 

Thanks! I'm at work now, so I'll try this when I get home.

 

Yes, I do, and I did try that, but to no avail. Thanks anyway!

 

Thanks again! I don't trust myself to delete anything--the instructions said "and/or" and there were 2 of each Upper and Lower, and I didn't know which to delete. So I downloaded from your site, and it works fine now! Thanks SO much!
