Windows 10: Why am I Getting Random Blue Screens?

I recently upgraded my pc with a new case, MOBO, ram, and cooler. Ever since I now randomly blue screen and for the life of me, I can't figure out the cause. I have been unable to reliably replicate the crash. Sometimes I'm able to game for hours without any issues, other times I crash boot up and crash again after a few seconds. Since this all started after the introduction of new hardware that was my first suspect. I tried different ram configurations, such as only one stick and different slots, but no luck. I then ran a memory diagnostic which came up clean. Followed by checking my SSD's wh

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.

• Did you get a STOP code?

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?
