Windows 11 computer keeps freezing after using for a while.

HP AIO screen freezes after using for a while. I can use the power button and turn off and back on, then it's ok for a while before it freezes again.

Greetings @AMM57 

Welcome to the HP Forum.

The first thing I would do if I were you would be to check your PC's hardware.

Check your PC's hardware using HP Diagnostics as follows:

Start the PC. Repeatedly tap the "ESC" key.

Select "F2". Run extensive system and component tests to confirm: a drive problem, a memory problem, or other component problem.

Let the Forum know how it goes.

Thank you for your prompt response. I had to download updated diagnostics, but have now begun the testing.  The first one says it’s 5 hours. Hopefully it won’t freeze during the test. 
I’ll provide an update as I progress through the process.
