Crashing every 3 hours of continued use? May well be your 360 overheating. Both Fallout games are VERY CPU & YOU intensive. I have both on my gaming rig, watercooled with SLI and it heats up more with these games than any other I play, including all Crisis games. Just a thought. I haven't updated, yet, is there any compelling reason I should NOT? Thanks for all the input and support, everyone.
