Depending on what event log size is configured and how long the event was created....you may or many not find it.
If you want to monitor and continue to monitor these types of events, I suggest you use other product like SCOM or get a 3rd party product such as Active Administrator where you can get email alerts etc to all these types of events or save them in a log for futrue reference.
