Have you run diagnostics?
Tap the ESC key after powering on. . Tap it once a second after you see the LEDs on the keyboard flash. When you see the startup menu, press F2 to run diagnostics.
Do not allow any updates if disk or memory fail, especially a BIOS update.

HP releases newer UEFI diagnostics periodically.
When you select F2 during boot you are requesting UEFI diagnostics.
There is an updated diagnostics package Click Here
Look for the phrase 'issues outside the OS',
Expand the'+'symbol and click the DOWNLOAD button.

If a component fails during the UEFI test then Click here to check warranty

That is not good. Does it flex when you hold it like this on?

If you hold it in both hands and flex it, does it freeze?  That indicates a hardware problem.

What do you mean by "move"?
