Sorry for the late reply.
STOP 0x07E - SYSTEM_THREAD_EXCEPTION_NOT_HANDLED is the specific code you are receiving.
This is a very generic error code and can be caused by a faulty RAM module, buggy driver or malwares. Please follow the below steps.
Boot the system in to safe mode with networking. This will give you internet access.
Set Windows to write small memory dumps in the event of a crash.
Download and install Malwarebytes free from the below link.
Run a full scan with it. Delete any infection it founds.
Try to boot the system in to normal mode. If you are getting BSOD, check whether there is .dmp files are created inside the C:\Windows\Minidump folder. Upload all the files inside that directory according to the instructions from my previous post.
Download and run Minitoolbox from http://www.bleepingcomputer.com/download/minitoolbox/
Run the tool and only select the following tick boxes.
-List last 10 Event viewer errors
-List installed programs
-List users, partition and memory size
Now click "Go" and post the output in next reply (or upload the result.txt with dump files)
Let me know your findings in next reply.
