Bluescreen Error Code: ef, 154, 7a and 3b

[DanikChekhovich]

I'm not sure why my laptop is blue screening. It started 2 months ago without any reason. Since then I have run various tests on my hardware and have found nothing wrong. I also tried a clean install of Windows 10 and have updated and downloaded all drivers. The most common errors for me are these 4 but the errors ef and 154 occur more frequently. Here is what I have from the reliability monitor:
