Hi guys, my computer underwent a whole ton of upgrades and I've reinstalled most of my games with success. The problem is, however, that Fallout 3 keeps freezing after 5 minutes to half an hour of gameplay. It just freezes, ambient sound an music still working in the background. Can anyone help me make this problem go away?

If it helps, my PC specs are:
Windows 7, 64-bit
Intel Core i7-2600K @ 3.4GHz
8GB RAM
Radeon HD 6950 with 2GB DDR5 Memory

Tried a number of fixes and it only takes 30 seconds instead of 5 minutes... f**k Fallout 3, I give up.
