If it is a ram problem, 6 gbs of ram isn't enough? I'm assuming you mean system ram, not video ram. if youre using windows xp, it should be fine. I'm using windows 7 64 bit and it eats up 4GB just on desktop. If youre using windows 7, i'd get more ram. I have 16 gb in my rig. also you need a 64 bit version of windows for it to see more than 3GB.
