I do not know if this can be helped but as some of you may know, Windows occasionally tries to explain to you why things broke. Why things happened like they did. Most of the time it is useless information of course. Mine popped up today with 30+ instances of Fallout 3 not responding. Minus one of them, the problem signatures were the same. I say 30+ because that is about how many times it has happened. I had issues getting the game to work at first but I believe I have that resolved.

I can link a DxDiag in this thread, or you can read it in my other thread that is doomed to be buried in annals of these forums. It can be found here.

I am not seeking help with the problem in that thread though if you happen to know what is causing that one, I would be most appreciative.

Thank you for your time and consideration.
