My assessment of your problem is based on possibilities and likelihoods - not by cold hard "this is the cause" facts.
There's just too much going on inside the OS to make statements like that - even with blame assigned by the debugger.
In this case, the blame is laid on a DirectX driver (dxgmms1.sys) in both memory dumps.
The possibilities are:
- that it's a 3rd party driver causing dxgmms1.sys to crash
- that there's a hardware problem that causes dxgmms1.sys to crash
- that there's a Windows problem that causes dxgmms1.sys to crash
Because DirectX is most often associated with your video sub-system - and because you mention updating your video drivers - we've got to suspect video issues first.
Try these free diagnostics. Please run them all - but concentrate on the video tests:
