Whenever I encounter such a problem, my first steps are to run Apple Hardware Test (AHT), and if that shows no problems (it’s far from foolproof), try a completely clean install of the OS to a blank drive. See if you can get any clues from either of these steps.
If you need AHT for your Mac, you can find it for many different Mac models here on GitHub: https://github.com/upekkha/AppleHardwareTest <https://github.com/upekkha/AppleHardwareTest> Let us know how it goes. You mentioned that occasionally your Mac refuses to start up. Can you describe the crashes you’re seeing? Are you getting the gray screen with a message that you need to restart your computer, or is it just a reboot with no warning?
