After you hear a second beep, your PS4 will boot into Safe Mode. Once the lights on your PS4 go out, press and hold the physical Power button on the front of your console for several seconds. To rebuild your PS4 system database, shut down your PS4 fully by holding the PS Button on your controller and selecting Power > Turn Off PS4 from the Quick Menu. Doing this will also cause your PS4 to check for updates for games you haven't played in a while, upon rebooting once the process completes. While this probably won't improve your game performance, it reduces the home screen delays that are common with extended use of the PS4. Instead, it tells your system where relevant data is for your games and services, making for more efficient access. Select Install Update, if an update exists. To rule this out, you'll have to check for updates to the game and install them if available. This process isn't as intensive as defragmenting your hard drive. If your PS4 is overheating when playing a specific game, the game software itself may be at fault. You might not know that the PS4 has a utility in its Safe Mode interface called Rebuild Database. If you're wondering why your PS4 is so slow, especially while in the menus, this option is for you.
