Being as there are several dumps, I recommend you view each report as opposed to me pasting a summary here ( as I would usually ). The stop codes you have encountered are typically driver based, however the vast variety of stop codes could indicate hardware or core OS corruption.
However there is a common theme across the dump files, the majority of them blame dxgmms2.sys - those are the microsoft DX graphics drivers.When this pops up, it's usually GPU drivers that are the fault,and I noticed that you have some video card drivers that are over 2 years old, you'll need to update these and this likely could be the cause of your problem.
