Windows 10: Having random blue screens and not sure how to diagnose.....

I am having random blue acreens. They have become more frquent an the last two days. I formatted my drive and reinstalled Windows 2 weeks aga to seeif that would fix the problem, but they are back and becoming more frequent.


Any ideas?

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.

 

Trying to diagnose random blue screens

Random blue screen errors in my experience are caused by the following, roughly in this order of likelihood:

1. Faulty memory (or a poorly-seated module). If you have multiple modules, pull one by one. You can also do RAM tests, but I find pulling modules faster unless the errors don't occur reliably enough to quickly know if things have improved.
   
2. Failing motherboard (particularly, bad capacitors). Bad caps are easy to spot as they bulge at the top, have obvious leaks, etc. If this isn't visible, running another OS on the machine can quickly eliminate/confirm this cause. If the MB is bad, another OS should crash too.
   
3. Buggy software (drivers, malware). Again, running another OS, booting to Safe Mode, anything that can get possibly faulty code out of the equation can help determine if this is the problem.

Hi,





Blue screens could be caused by problems with your computer’s hardware or with its driver. Still, we

• Did you get a STOP code?
