Hi,
Kindly note that even a properly functioning system will show various warnings and errors in the logs you can comb through with Event Viewer. Assuming your PC is working properly, you can pretty much ignore the errors and warnings that appear in the Event Viewer, thus, we always suggest to dig event logs when there is the actual problem for windows.
Moreover, different behavior of problems will guide you to check different folders of the event viewer structure. You could also check the event logs based on the time occurrence of the issue. Then search the internet with the exact event ID and the general description to narrow the down the causes of the problem.
Here is an example of How to Use Event Viewer to Find Your PC’s Boot Time
