post genius update: the guy decided that its bad ram after opening up and seeing that it has kingmax ram in it (note: i;ve also realised i've been conned by my reseller! i've ordered a bto and they gave me stock with two generic sticks... granted that will all that ram it still cost less than the 2gz white model here...). he then said...' the last 3 mb i saw that had your problem had ram problem, therefore since you are not using apple ram, this must be your problem, announced that its going to cost me 480 quid to rebuy 2gig of apple ram and said... of course you can try 3rd party again, but why won't you.
so guys, is kingmax ram that bad? the reseller i got the computer from also ran off with my apple stock (my mom got it from me in hk where everything is cheap) so i can't even bung them in to see.
then the guy told me off for playing jedi knights the whole weekend because that exhausts the system. Hello! its like a 3 year- old game...
so what next dudes?
