First of all, thanks for the extensive explanation.
The thing is that FNV started cracking up after short play sessions: between half hour and forty five mins... Sometimes it was shortly after the start and one time it went back to the xmb before it even got into the game; from the load screen. In fact I remember being amazed one day when I was actually able to play a couple of hours without having to restart.
I have to say that I actually take pretty good care of all my electronics. The only bad thing I do is that my friends and I smoke around it, the sticky stuff too. But otherwise I keep it clean, clear, cool, and dry.
It plays all the other games (not connected to Bethesda at least) like clockwork, even Blops which is supposed to have a lot of issues too.
I know I said it before but experiences like this make me want to just get a really good pc when the next gen rolls around.
It might just be a specific game - some games are much harder on the hardware than others, and the additional work can drive hardware temps through the roof. I remember when Crysis first came out, the rig I was running could barely last 15 minutes before shutting down from overheating . . . whereas my current hardware doesn't even hiccup at that title with in-game settings maxed out, and runs at comfortable temps for hours.
It sounds like there might be some game bugs causing the crashes, but it also sounds like the primary culprit is simply heat. If you're willing to crack the console open, you'd probably be amazed at how much dust has built up inside, and smoking makes it a lot worse:
Pretty nasty, eh? Big reason why I don't smoke around my hardware. The tar makes dust stick even thicker, and makes it a major PITA to clean out (a can of compressed air usually won't work to break that free).
Also, between the processing cores (CPU and GPU) and their cooler, there's a layer of thermal paste that helps transfer heat from the core to the cooler . . . over time, the paste will dry up and break down, requiring it to be re-applied at some point. I'm not sure, but I believe this is a fix for the "red ring of death;" I can say that for computers, it's considered by a lot of "power users" to be "annual maintainence" (along with cleaning out dust, etc.).
