STALKER continuously crashing again

So now after having to restart after a 6 hour save I got back to my point and continued past that point about 4 hours.  Now my game is continuously crashing again so I can't really do anything about it.  If I complete a mission it's an automatic crash, pretty much anything crashes it.  Ahh I hate this because I really love playing Stalker, but I don't know if I want to play it for awhile now.  It's very frustrating.

So about the game now.  It's very fun, they've made a bunch of visual improvements that make the game look great.  The atmosphere is still all there, it's great.  Faction wars seems cool.  I'm a Dutier, always play on the Duty faction when doing my first play through.  I eliminated the Freedom base, and captured all of the little outposts in the garbage and dark valley areas.  The updated PDA is nice.  Tracking missions is much easier and far more organized.  You can see the movement of allied and enemy squads and the destination they plan to attack.  Lots of cool updates.

If you've played you also know that the bandits now actually stop you and take all your stuff.  Most of the time you're completely outnumbered and there is no way out.  I don't know how I feel about the bandits.  It makes me not really want to do any side missions since I know my stuff will get stolen.

And then there are the crashes.  All I have to say is:
 Urghahahhhaghh!
