Client Crash everytime

Hi,

I did download few days ago WOTLK client from the site and it did wrok perfectly. But couple days ago i did download TBC client and everytime i click Wow.exe i get black screen and whole computer will freeze so i need to hard reset computer. Is that known problem? I would like to play tbc.

I have windows 7, GTX 1060, 8 GB memory, processor i5 something (i'm in work now so can't check it)

Try reinstalling your video drivers, after that, try redownloading the game, maybe you changed some files.
