Windows 10: Random blue screens

My computer will randomly blue screen every once in a while without warning and most of the time when I am away from it. This has continued to happen even after I did a fresh install of windows. I have done a memory test and no errors have popped up. Here is a link to all the dump files from the blue screen events.

Trying to diagnose random blue screens

This is a Windows 10 Professional desktop, built seven years ago. It is starting to fail, with almost daily blue screens, and I'm trying to guess what part is failing. The candiates are naturally the motherboard, a RAM stick, or a video card.

The errors are almost always different, and there is almost never a culprit announced. Here are some examples:

• MEMORY_MMANAGEMENT
  
• IRQL_NOT_LESS_OR_EQUAL
  
• SYSTEM_SERVICE_EXCEPTION
  
• KMODE_EXCEPTION_NOT_HANDLED (mcdbus.sys)
  
• SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
  

Eventually I will have to start removing all parts one by one, but I was wondering if these errors might suggest which part to check first.

Hi,





Blue screens could be caused by problems with your computer’s hardware or with its driver. Still, we
would like to know more about the issue. Please clarify the following:

• Did you get a STOP code?
• Did you install any hardware or driver recently?

Random Blue Screen Errors

On my Lenovo-All in One, I get random blue screen errors when the computer sits idle for a couple hours.

STOPCODE: SYSTEM THREAD EXCEPTION NOT HANDLED nvlddmkm.sys

I need to power off the computer, but each time it successfully reboots, fortunately.

Any suggestions?
