Welcome to the 10forums.
I noticed you are running Windows 10 TP (Technical Preview a.k.a. Insider Preview)
The crashes are caused by the Intel graphics drivers, unless this is for testing purpose you shouldn't run the Windows 10 TP version.
OS Name: Microsoft Windows 10 Pro Insider Preview
The Windows 10 TP version is very unstable, you should always expect problems with the TP version.
