game broken

Whenever I try to play the game, ( I downloaded Burning Crusade and used BitTorrent ) the screen is black and my computer becomes completely unusable and I can only restart my computer to be able to use the computer. Whenever I try to open the wow application in the folder. I tried the launcher one as well but it yields the same result. I could really use some help with this because I was hoping to play this private server. Thanks.

Are your GPU drivers up to date?
