ok, first my desktop was crashing ALL the time,, took 4 to 6 loads to get into a game, crashed everywhere from after clicking mw 32 bit to loading into a map.. by the time I got my 2nd system and gave the first to my son, the desktop wasn't crashing ... no, I didn't change anything..
New system... after I got everything setup,, I'd crash randomly while playing every 10 to 50 min... tried a bunch of things before giving up and just hopn' that .3 would be more stable for this system.. but.. seems the crashes have stopped,, about a week ago *knocks on wood*
did the devs sneak in some AI that is self repairing?!?

lol
