Windows 10: Random Blue Screen

Been getting A LOT of random BSODs ever since i installed the last major windows update (about a month or so) so far i am positive that i've got more than the entirety of 2018 (one or 2 bluescreens). i'm not sure which bit is causing the blue screens but the fact that it's happening at a very increased interval post-update is a big sign. it always happens randomly so it could crash when i'm playing a game (heavy load) or it could crash while i was working on a word document (very low load)

Blue Screen

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?

For basic troubleshooting steps to resolve blue screen errors, we suggest checking out this
article and simply follow the steps.



Feel free to contact us if you need further help.

 

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.

 

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?
