@manolissagias, Welcome to HP Support Community!

Follow the steps to perform an extensive system test-

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second.

When the menu appears, press the F2 key.

3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

4. Click the Extensive Test.

5. Click Run once, or Loop until error.

While the test is running, the time remaining and test result for each component are

shown on the screen.

6. If a component fails a test, write down the failure ID (24-digit code) so you have it

available when you contact HP Customer Support. The information is also available in

Test Logs on the main menu.

Keep me posted.

@manolissagias, Welcome to HP Support Community!

If it happens on all user profiles, it's most likely a windows OS issue. I'd suggest you back up all files and perform a system reset. Refer to the document HP PCs - Resetting Your Computer (Windows 10) for help.
