Open an admin command prompt. Enter the command below and make note of where it is stored. It is a log and may be hard to understand so you may want to make it available.
The way I check it is to try to find common events when the system is working correctly and when it isn't. Keeping accurate records of times when events occur will help analyze the events in the log so you can tie the real world occurrences to the log.
