freezing/bsod while gaming

Built a new machine.
powercooler 4770 video care
4g super talent ram
1 tb WD green
dvd burner

This was a brand new build with win7 64bit build 7100 installed from the beginning. Win7 runs perfectly except from time to time while playing atlantica online (a mmorpg that shouldnt be too intensive, i used to play on 80% settings on my old amd 3000/9800 pro)
Sometimes it will play for 2 hours without an issue, sometime 15 mins. in 1 of 2 things will happen. It will either freeze the video, still have music and will only respond to reset button or it will bsod.

here is the recovery message after a restart
