System Spec:
Windows 7 64bit
Intel Core i7-2720QM CPU @ 2.20GHz
RAM 8GB
AMD Radeon HD 6970M

Bought Game of the Year Edition on Steam. What happens is that I get out of Vault 101 and enter the first town. When I go into a room and pick up a gun, it freezes with the sound still going.

Any help is much appreciated. Thanks in advance.
