This could be caused by a defective/failing CPU, flaky power supply or possibly a device driver.
The 4/29 dump shows a problem with iaStorA.sys.

The 4/29 dump also indicated a problem with your Nvidia card or driver:
Code:

*** WARNING: Unable to verify timestamp for nvlddmkm.sys
*** ERROR: Module load completed but symbols could not be loaded for nvlddmkm.sys

You already have the latest driver but you could try this:
Remove and install latest Nvidia drivers:
I suggest completely uninstalling the Nvidia display drivers using Display Driver Uninstaller (DDU) from WagnardMobile (near bottom of page) then get the latest driver for you Nvidia card here: NVIDIA Driver Downloads
Then do a custom install of only the NVidia graphics driver and the PhysX driver.
See if that gets rid of the problem.
