Personally i think your PSU is not powerful enough the ATi 4850 consumes something like 80/100 watts by it’s self. So i would recommend you get a better PSU especially with a Q6600 in your rig and that consumes like another 100 watts of power which leaves you 180 watts of power for everything else. Get something like 500watt+
