Replying to Computer related question. Need help.

So i was bored one day and started downloading Fable: The Lost Chapters via a Torrent. It downloaded just fine, and installed just fine also.

Now when i went to play the game it started fucking up. After about 8 minutes, the game moves areas and it auto saves. It starts to load, then screen just goes black. Sound is still there and computer is running fine, but game is stuck.

So i decided to DL another version of the game(first one was a self extracting .exe and this new one is an ISO).

This one goes along fine, but at the same part, it does the exact same thing. So i uninstall this one and decided to just bite the bullet and go buy the game for $20.

Now i install the LEGIT copy of the game and it does the EXACT SAME THING.

What the fuck is happening? Are there still corrupted files somewhere in my system? What can i do?

Thanks and +karma for help
