I built this computer in May (2012), here are the specs..

Seagate Barracuda ST31000524AS 1TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive

Microsoft Windows 7 Home Premium SP1 64-bit - OEM

The computer is hooked up to a Antec 1100, and monitor is a like 20" Vizio connnected via HDMI.
I have downloaded all the latest drivers and run a Tuner GPZ? log to watch temps and such. Nothing really stands out. The only thing I can think of is it might be a RAM or GPU problem.

I'll be playing a game, usually on steam, sometimes not. The time varies, sometimes I can play for hours and then it wil happen. Other times, it will happen within 15mins. Just last night I got the "blue screen of death" twice for unknown reasons. I'm just trying to find out whats wrong while I still have some warranty's.

Any and all help or advice will be greatly appreciated.
