Quit To Desktop when entering certain areas

[Vraal]

I have an issue which is severely limiting my ability to replay Fallout 3. Sometimes areas of the game will become inaccessible to me, because as soon as my character enters a certain place, which can be both a marker and just a radius of Wasteland, the game just dies. It lags for a few seconds, freezes, possibly skips a few frames, and bam, it's dead. No error, it's just gone. Occasionally it hangs the system, but QTD is far more common.

I'm running about twenty mods using FOMM, but i think i had the problem even before i had any mods running. I've had it occur in the following areas:

Fort Independance: Cannot get to Casdin. ARGH!

Exiting Vault 101 after sabotaging the generator in Trouble on the Homefront (had to coc back to Megaton or would have been stuck forever)

The area between Springvale school and Big Town.

Cannot fast travel or walk there. This yields the same result. Once an area is like this, it's permanent; the character is unable to go there forever.

 

Just wondering if anyone may have had a similar issue, would really apprerciate suggestions as to whether it could be just the mods, my version of Fallout (completely unpatched) or some random thing which only afflicts MY game. It's getting reeeeeally annoying, especially in the case of Fort Indpendence, which is where i get all my frags.

i got out of there. 2 of my companien where responsible for it jessi and Kelsey, i disabled the 2 mods and i could move out of the area, had the same problem at Springvale school, its a waste i would like to keep kelsey but with the i cant play (first i tryed only to disable jessi or only Kesley, but that didnt work i had turn both of them off, to get out of there). maybe it helps u 2 if u have both or 1 of that companien with u turn them off and maybe it solves ur problem 2.
