Google the error code to see what it says it's related too, generally if event viewer has many many critical issues of the same type it points to a hardware issue, if only a few in the time stamp relevant to when you had the issue then more likely a software one.
I'm not really technical enough to trouble shoot that myself, but I do use event viewer to try to work out issues at times when i've had them, sure there will be info online that can help you at least narrow it down.

it might take you some leg work to route the issues out, but generally I'd only look at the critical errors in the time frame your aware of there being an issue.
the bug check in my view is a common one, so maybe not worry on that too much tbh.
If you can't seem to find anything relating to something that fits with the issue you've had focus on the Bios and XMP for the memory or setting the right timings for the ram, and give it some time to see if the issue happens again, unless it's still happening now, then someone smarter might be able to help you if it's more urgent.
It can be many things, sometimes driver updates that you've done or that need to be done or a device fault, it's kind of a minefield really, I always wanted to do a real indepth course on software, but unforutnately I'm self taught like most people so we do what we can
