The version I have of windows 7 is a pre-release version of it. This means that every time i logg into my windows account, I'll get a message saying This pre-release of windows has expired. To keep using windows, back up your files, and then try to install any released version of windows 7 ultimate.''. This also means that it's not possible for me to use any of those automatic windows update and my computer restart itself automaticly after exactly two 120 minutes. I simply haven't got enough money to buy a new version so it's never been done.
So your windows isnt capable of updating itself at all? Even manually? You havent gotten all the security updates, stability updates, KB updates, bug updates, redist updates, etc, etc, since some pre-release date?
If your windows version isnt current then that may be the problem. Just because you've been fine up to know doesnt mean you will never encounter problems. BTW if the above is true then I would strongly recommend
you get the full version of windows since you are making yourself vulnerable to attacks. Those security updates are important. Does IE allow you to download updates manually?
If you have no mods installed (vanilla) then it shouldnt be happening. This isnt a common issue and those who have had it resolved it to a mod they were using.
When you say your game is freezing can you get into the task manager to kill it or do you have to reboot? What does your event viewer say? Start menu type into the textbox at the bottom 'event viewer'.
Look under applications. ANything relating to falloutnv or anything time/dated when the freeze happened.
Have you tried a clean boot?

ALso here are some updated run-times (there are also windows auto updates for these 2 which may be causing problems):

It may be the only thing you can do is reinstall the game from your CD and dont let steam update it.
Try this to get it to run from the CD:
Using Steam launch options to install retail games from disc
1) Log in to Steam and click on Library.
2) Right-click on the game, select Delete local content, and confirm. ALso make sure to delete the falloutnv directory and saved game directory (again backup saves)
3) Insert the first disc into your computer.
4) Close Steam (Steam > Exit).
5) Press Windows Key + R to open Run
6) In the Run window type:
"C:\Program Files\Steam\Steam.exe" -install E:
Replace E: with the CD/DVD drive you are installing from if is not correct.
Replace C:\Program Files\Steam if your Steam installation is not in the default location.
Press OK. Steam will launch and ask you to sign in if you do not have your password saved. Your installation should continue from the disc.
I think even during installation you should be able to go to the properties for falloutnv and find the update tab. Select do not auto update this game.
This isnt guaranteed to work though. You may have to put steam into offline mode or disable your network adapter. You'll have to do some of your own
googling for that though.
