Had a moment to think about this and remembered my own nightmare with a lagging Pro. A couple years back, mine started freezing during every cutscene in Horizon. I tried the full reset like the other guy suggested, but the lag came back within a month. I realized the stock mechanical drive was basically dying from years of heavy use. You might want to consider these steps before you wipe everything for good:

• Try Rebuilding the Database in Safe Mode (Option 5). It won't delete your games but fixes the file index which usually cures the lag.
• If it still stutters, your hard drive might be failing. I would suggest backing up your save files to something like a SanDisk Ultra 128GB USB 3.0 Flash Drive as soon as possible.
• Seriously consider swapping the internal drive for a Samsung 870 EVO 1TB SATA III SSD. Changing to an SSD was the only thing that actually fixed my crashes and the load times became insanely fast. Just be careful with the ribbon cables if you ever open it up to clean the dust out while youre at it... they are super fragile.

If you're experiencing issues with your Sony PS4 Pro and need to do a hard reset, follow these steps to get your console back up and running smoothly:

Step 1: Power off your PS4 Pro Start by completely powering down your PS4 Pro. Press and hold the power button on the front of the console for about 7 seconds until you hear two beeps. The power indicator will blink a few times and then turn off. Your PS4 Pro is now powered down.

Step 2: Unplug all cables Once the console is off, unplug the power cord from the back of the PS4 Pro. Also disconnect the HDMI cable and any other cables or accessories plugged into the console. Leave everything unplugged for at least 2-3 minutes.

Step 3: Plug the power cord back in After a few minutes, plug just the power cord back into your PS4 Pro. Don't reconnect the HDMI cable or any other accessories yet. Make sure the power cord is firmly plugged into both the console and the wall outlet.

Step 4: Boot into Safe Mode With only the power cable connected, press and hold the power button again for about 7 seconds until you hear two beeps. This will boot your PS4 Pro into Safe Mode. You should see a black screen with white text giving you some options.

Step 5: Select "Initialize PS4" Using your controller (plug it in with a USB cable if the batteries are dead), scroll down to the "Initialize PS4" option and select it. This will bring you to another screen with two options:

1. Quick Initialize PS4
2. Full Initialize PS4

The Quick option will just wipe data and settings while keeping system software intact. The Full option does a complete wipe and fresh reinstall of the system software. If you're having software issues, do the Full initialize. Otherwise, Quick should suffice for most hard resets.

Step 6: Confirm initialization Select the initialization option you want and confirm it on the next screen. The initialization process will begin and may take anywhere from a few minutes to over an hour depending on which option you chose. Let it complete fully.

Step 7: Set up your PS4 Pro again Once initialization finishes, your PS4 Pro will reboot and take you through the initial setup process again, just like when you first got the console. Follow the on-screen instructions to set your language, connect to WiFi, sign into your account, etc.

After setup, your PS4 Pro will be reset to factory defaults. Reinstall any games and apps you had before. Restore your game saves from PS Plus cloud storage or a USB backup if you have one.

That's the full process to hard reset a Sony PS4 Pro console! It may seem intimidating, but just follow these steps carefully and your console should be reset and working properly again. Be patient and let the initialization process fully complete. Good luck!
