It recently just stopped working. It happened a week or so ago, it only reads CD's. If I put in a DVD-ROM and try to run it, it says to insert a disk, and pops open the tray.

I checked the progam drivers or whatever, and it just has a CD reader installed. I got my laptop last year, it's worked fine up until now.

Anyways, how can I get it working again?
....I don't know how to do that lol

It's a Gateway NV52 and it runs Vista.
Which I am blaming for all my problems.
