For some reason, completely random and unknown to me, my Morroblivion installation decides to crash on every cell change and whenever I fast travel or travel by ingame methods. This problem appeared randomly, and I had not done anything between last playing it and before the problem appeared that could have possibly caused this. It's ridiculous! Anybody have any ideas of things I could check?
Things I've tried:
1) I recently flagged my game to use more than 2gb of RAM, because that was stupid... I have 8gb so I want to use at least half of it. But I reverted those changes and it didnt help.
2) It's not the load order, I checked that
3) I'm running 2 ati graphics cards with crossfire, but despite the different settings it crashed every time.
4) It's not Cell Buffer Overload, this crash happens right when I start the game... There's no information to overload with

Crashing on cell switching is a common problem. I would think first thing to try is disabling crossfire and/or removing one video card. Also, if you are using more than one monitor, stop doing that...
