Windows 10: Windoes 11 goes to locks screen at random

Hi, a Lenovo Win11 64-bit PC is was running fine a few mounts, then it started going to the locked screen after 1 min. there was no way to change the 1 min mark in the advanced power settings - so I followed the instructions and corrected the regedit "pathway" DWORD - advanced, that gave me the optione to change it from 1 min to 10 min.now the PC goes to the lock screen randomly - sometimes its an hour , others its as low as 20 seconds. the power settings are set to above 15 minand the pause screen is set to 10 min - with a 3d motive , so its not blank. the Lenovo Vantage options are turned of

Random Auto-Locking of Computer Screen

So for some reason my computer is at random intervals going to the lock screen. Sometimes it immediately goes to lock screen after unlocking (no password) it by pressing Enter twice it logins in again and then again goes back to the lock screen sometimes within anywhere from 1 to X seconds after login.

I have tried disabling sleep options. And also reinstalled windows from a new bootable USB ISO I got from Microsoft. But after running it for a while it started experiencing the same automatic locking.

I also tried another pc screen and the same issue. I then brought in a new computer and connected to the Sony TV screen which my old computer was connected to and now that computer has the same issue. I then connected the new computer to the pc screen and it works fine. So then I connected the old pc to the pc screen and it still had issues. It seems more common when connected to a TV. I have also tried a different HDMI cable.

Any suggestions? Can someone explain what is happening or how to even diagnose this issue?

 

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??
