Hello. Earlier today, my brother had difficulties with Internet Explorer. The program wouldn't shut down properly, so he decided to log off his profile. However, it did not log off successfully and it went to a screen with said "NVIDIA Boot Agent 249.0542". I was unable to navigate away from the screen, so I just manually shut off the computer, then turned it back on. Everything seems to be working fine and there's no record of anything serious happening around that time. Is there anything to be concerned about any of this? Thanks!
