CD-ROM Problem

Ok, so this morning i saw that the lights on my case were off.
When i checked inside the case to see if any wires had disconnected i had no luck, but i did figure out how to get the lights back on by just moving around the wires.

Later today i tried playing WarCraft 3 Frozen Throne but it wouldnt read the disc(I did play it the night before with no problems). Now when i tried puting in other discs it seems like it does read them in My Computer because i can see the icon of the cd-rom drive change, but it does not show any files inside.

Could this be bcause i had messed around the inside of the case earlier? Or i change something by accident in the CD-ROM settings?
Please help me.
