Starcraft 2 lockup black screen

[suprattarga]

Alright I am officially out of ideas, I have been playing Starcraft 2 since it came out (about 2 to 4 times a week) about 2 and a half weeks ago my computer locked up (black screen) and had to reset. After testing everything I decided just to build a new computer. So new build is listed below

Anyway the issue I am having is whenever I play a game (anywhere from 20 minutes to 1 hour and 15 minutes) the system locks up displays a black screen and I have to restart the computer, I have no idea what it could be please help.

Side note; not sure if this is an issue but Starcraft 2 does not "recognize my system" so everything is set to medium or low settings (aside from the GPU which defaults to the highest settings).

OCZ agility 3 120 GB- SSD

I think it's not a matter of being ati fan or nvidia fan, it's just that you have the latest generation card that hasn't been out that long. Amd has always been slow on their drivers, or I should rather say slower than nvidia. But both companies get problematic drivers.

Right I simply mean I'm rocking the Nividia card now, every computer I've had before as had an AMD card and have always had good luck with them aside from this time.
