a little help please

now this is going to sound like a stupid ass question and most likely belongs in video games blah blah, blah,

but what i would like to know is why the fuck my PS3 continusly crashes when playing (cue hate) CoD blops 2

i understand the importnace of keeping it in a up right postion allowing for maximum airflow, etc etc etc

any ideas guy ?

Had a look at Google and it seems that the game causes the freeze

Here is link to CoD blops2 thread about some else with the problem
