So I'm running Vista Ultimate, and have had no problems up with the CD drive whatsoever. But now, seemingly randomly, when I click on the "CD Drive" icon, it says "G:\ Application not found." When I go into My Computer, I click on it and it says the same thing. If I have a game CD in that is already installed, I can click on its icon and it will run fine, and whenever I put a CD in, it sounds like it's spinning. I have looked all over every forum I could find, but I haven't found a good way to fix this (other than replacing it, which will be a pain). I'm not awesome with computers, so please simplify any explanation as much as possible.
