Hello PCHelpForum. For the the past months some bsods are killing the joy of playing on my new pc, they all occur after around 4-8 hours of gaming. I did around 4 os installs with proper drivers and I just can`t get rid of it and all are caused by the driver dxgmms1.sys. I tryed different versions of video drivers, new bios for my motherboard, 4passes in memtest86+ with no errors, firmly placed my hardware in their place twice. Also all components have normal temps. System Specs: Mobo: Asrock 970 Extreme3 CPU: Phenom x4 Phenom 965 BE GPU: Gigabyte HD 6870 windforce RAM: Patriot 4gb 1333mhz (1 stick) HDD: WD Cavier Blue 500gb Sata3, 16mb PSU: Seasonic S12II-520w Bronze Case: HAF XM Today I made a new os install and I was very careful with what drivers and software I installed and after a few hours I got a bsod. What could be the problem? Some friends are saying it might be the video card or the motherboard.
