Fallout 3: Completely Different Freezing Issues!!??!!

I know a lot of people have had freezing problems, but none of the boards describe the problem that I have.

[PROBLEM]
The game runs smoothly most of the time, regardless of the video settings I use, except at random times, (indoors or outdoors, looking at PIP or even VATS) the game will freeze. But only for 6 seconds, and always 6 seconds. Then play always resumes to normal for a few more minutes (or a few more seconds), and it freezes again. This seems to happen more often the longer I play.

[WHAT I'VE TRIED]
Following fixes from some other posts, I've added Fallout 3 to ffdshow's exceptions, and when that didn't work, I removed the K-Lite codecs altogether. Still freezes.

I've installed the latest video card drivers too btw, and drive indexing is off as well.

Anyone have the same/similar problem? Anyone have a solution?
Thanks,

The game is pretty buggy.

I have had VATs lock up on me, casuing the game to freeze, other friends have had saves been corrupted.

I see you fixed your problem already but i'll post my small trial and error and solution that worked for me to help others, I had stuttering problems that felt like framerate problems but I was always above 40FPS, I also had freezing issues that seemed to occur at random. I read in the official forums a suggestion to force Vsync off in the driver setting and that did fix the stuttering problem for me but the freezing still occured and everytime I used VATS I blue screened.

So that didn't work out for me but maybe some of you can try it. The newest drivers on the Nvidia website didn't work for me either so I decided to try some beta drivers 180.43 which fixed all of the problems for me and the game run perfectly fine, no stuttering or freezing. For ATI users best thing I can say is get the latest drivers, but I hope this helps.

I have that type of freezing issue but then after awhile it just discolours my screen to liek a blue and red and freezes up my whole computer does this to any 3D game I play ive updated my Graphics card and everything.....if anyone here knows what t odo please help...
