i had a problem very similar to what was talked about in the first post. IF this problem has been solved, sorry kinda late on time and didnt read all the post. my problem was my memery, i had a gig of ddr 3200 running at 400 Mkz( i think that part is right, any way i had to underclock the mem to somewhere between 333- to 340ish i think, and after that it ran great no more crashes during gaming, like u i would crash in games
