Can't view Windows Explorer

Hey. All I did was put in a DVD-RW disc, watched the video I had
recorded from the TV and took it out. Now Windows Explorer wont work and
my computer is running incredibly slow. Can you help or suggest
somewhere I could look for help? I've looked around a bit but still
can't find an answer to this.

I've attached a picture of what it looks like.
