every time I turn on my ps3 no matter what game it is it will freeze up after about 30min-1hr of play time. the only two games i play on it are Assassin's Creed and Warhawk. earlier Warhawk froze up on me for the first time and since getting Assassin's Creed it has frozen up on me about 4 or 5 times. does anyone know the reasons for the all of a sudden freeze ups?

would you guys rather play assassin's creed for the ps3 or the 360, i am told that there are more glitches and crap like that in the ps3 version but i havent noticed any yet. my friend says that there are little to no glitches in the 360 version...i would like your oppnion does it or does it not matter if there are glitches even if there not noticeable?
