This issue can be caused by the video adapter driver. I suggest: 1. Download the latest driver from the following website and install it. NVIDIA DRIVERS 196.21 WHQL Important Note: Microsoft provides third-party contact information to help you find technical support. This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information. 2. Turn off any graphic optimizing related programs if they exist. 2. If you turned on Over Clock, please turn it off.Arthur Xie - MSFT

Thanks for the reply. I tried the suggested driver and same issue bsod dxgmms1.sys. Also no overclocking and graphic optimizing programs what so ever

I think i fixed this issue. first i turned on enhanced intel speed step in the bios( dont know if that was the root cause but it slowed it down a lot) microsoft has issued a hotfix for this problem (Windows6.1-KB979444-x64) apparently it has to do with the power management not functioning properly. so far so good installed it today an i went from haveing 20 - 30 events a day in the viewer to just 1 in 36 hours (dns error) hope this helps! btw http://www.nirsoft.net/utils/blue_screen_view.html helps alot!!
