Disc drives not reading discs + ERROR 1719

Ok. #1) My disc drives are not reading discs. Trust me, there's nothing physically wrong with them. May be an issue with the drivers...I don't know. This all happened overnight. I also have been getting "Error 1719; something about the Windows Installer". Also, pc keeps completely freezing up when I right click my disc drives in "my computer". I have to power off & back on to get it going again.

Prior to all this, I did run Malwarebytes scan & "fixed" everything it found. I'm thinking I may have deleted some important registry stuff or drivers or whatever on accident. Please help me out.

Another thing...I've been having the hardst time getting this Nero program off of my pc. It wouldn't allow me 2 uninstall from add/remove, so I started just deleting every folder/file I could find that said nero anywhere on it. Yet, still it remains. This nero issue is of secondary importance to me. But if you could help me completely remove it, I'd appreciate it.

Heres my hijack this.
