I' m getting a blue screen in windows 7 ultimate 64 bit in dxgmms1.sys pretty often. I've tried updating all my video card driver(sapphire radeon hd6770) , my motherboard driver and still can't get rid off the BSOD. I've also tried chkdsk /r in ms-dos and I still have the problem.
After chkdsk , I've tried a scan with sfc /scannow command and Windows Resource Protection found corrupt files but was unable to fix some of them.
I've attached the minidump file. Please let me know if there's anything else you need.
Any help will be greatly apreciated.
