Desktop all in one goes to Lock Screen every 15 seconds regardless of being in use

[Assisi7]

Hello all, my desktop has been restarted multiple times, and is fully up to date with updates. My desktop continues to go to sleep on me every 15-20 seconds. I will be using it, and then the screen will black out. I can easily sign back in, but as you can imagine this is quite annoying. My sleep settings are at 30 minutes, and it has not done this before. Any suggestions?

@Assisi7 -- within the Windows "power" settings, there are two timers:

* minutes before the monitor goes "dark", by entering power-saving mode,

* minutes before the whole computer goes to "sleep".

What are your 2 settings?

Or, it could be a fault in the video-output hardware from your computer.
