CD Drive Not Working

The CD Drive on my Lenovo B570 Laptop refuses to read disks. It started a couple months ago, when it wouldn't read Halo 2 (PC). I asked around, and the general consensus was that it was an operating system clash.
But now it's refusing to read simple disks, like movies and CDs. I've even tried hooking up an external optical drive that I have, and I'm still having no luck.

Any ideas?

edit:

Can your lenovo be sent in for warranty?

If no, there should be a button or another method to return it to its original factory configuration (look it up in the manual)

Also, you didn't mention what exactly happens when you insert the disc into the drive.

Does it start to spin, windows doesn't show it or does it show it but it cannot be accessed.

Could also be a virus, depending on what happens when you put that disc in.

That's exactly what happens

And no, the warranty has expired.

And I don't want to factory reset it for a thing like this. I'd have countless hours of games to reinstall, not to mention filles that I would lose becasue I'd forget to put them on Google Drive or a flash drive
