screen display going off/shut down

[j2kappliances]

i cant seem to keep the monitor/computer on. 

When i press off the whole thing shuts down. 

i need the computer to be running all the time, but i can seem to find the setting to do it. 

and once the screen goes off, you turn it back on and it has totally shut down. 

please can anyone help?

Thank you for posting on the HP Support Community.

Let's perform HP PC Hardware Diagnostics and run the Fast Test.

1. In Windows, search for and open the HP PC Hardware Diagnostics for Windows app.

   If this app is not on your computer, download the latest version from the HP Hardware Diagnostics website.

2. On the main menu, click System Tests.

3. Click the System Fast Test tab.

4. Click Run once.

   While the test is running, the time remaining and test result for each component display on the screen.

5. If a component fails a test, write down the failure ID (24-digit code) for when you contact HP Customer Support. The information is also available in Test Logs on the main menu.

And, also update system Bios: Follow steps from the link: https://support.hp.com/in-en/document/c00042629

Hope this helps! Keep me posted for further assistance.

yesterday i set the screen to never go off. 

But this morning it was off again, and rebooted up when i turned it on.
