Fallout 3 freezing randomly

So the last few days theres been a big sale on Steam for all kinds of games. I've bought over 20 games for under $70 and one of these games were Fallout 3. Now I'm not new to Bethesda "incredible" work on the stability of their games. So the game started freezing when I started talking to Gob in Moriarty's Saloon (after about 40 minutes of playtime). The game froze, and i tried to open task manager to close the game, but the game looked as if it went into windowed mode but was enlarged and was black. The sounds were still going on the background. The second time was when i was about to exit the saloon, and the third was when I was looking for Colin, and the fourth was when I entered a house doing the quest "Those!" and the fifth time was when I was in the Wilks' house doing the same quest. Now whenever I load the quick save I had in that house I freeze after a few seconds. I'm running Windows 8, I've installed Windows games live and I've configured Fallout.ini and downloaded d3d9.dll. Nothing worked. I don't think you guys need my specs, but if you do I'll gladly give them. Thanks for helping

The same happened to me when I installed tons of mods. Now my question is that do you have the original fallout 3 or fallout 3 goty edition? Because the latter contains dlcs and even if you have not installed any mods maybe the content in one of those dlcs is giving you trouble which is a low possibility but still worth a shot. So try disabling those dlcs. Double click your fallout 3 launcher then data files then uncheck some of the esm and esp files. Don't uncheck fallout3.esm and fallout3.esp since they are the original files. You'll get the idea.

@alim298: I do not have Fallout 3 GOTY and I don't have any mods installed.
