Recently, my PC has been shutting down on its own. I have scanned my PC for viruses, but none were found. While playing games, my CPU temperature is also normal (75-78 degrees Celsius). I am currently using an app that prevents my PC from shutting down on its own, but I do not think I should use this app for an extended period of time. I have watched many videos on YouTube, but none of the solutions have worked for me. Can anyone tell me what the reason for this might be?
