Well I currently am running, ati radeon 6850 hd 1gb graphics card, amd 965 phenom b.e. cpu, 8gb ddr3 1600 ram, on a windows 7 x64 o.s. all put together on a m4a77td/usb3 motherboard, question is, the games run fine, perfect, crysis on ultra, but at random times with different games, one for example is brink, it bogs down or the fps drops low, very low, and after 3 to 5 minutes of that, it returns to normal state, and yes everything is up to date, including the motherboard, any help would greatly be appreciated, btw the pc is 2-3 months old
