Recently, I have BSOD when play game. I sent my asus gtx 670 to RMA department,but I still have BSOD after receiving back from them. The yellow bottom of PCI is shorter than the other, is it normal? The yellow on the right of PCI is shorter too I keep have nvlddmkm.sys, and dx.sys or something when play game. I have NTOSKRNL.exe while prime95+furmark to test stability. What wrong with my pc?
