Random computer shutdown

[TerryN10]

My computer randomly shuts down.  The light is still on the computer but nothing is on the screen.  I manually restart the computer and it takes about 15 minutes to get a functional desktop. This happens about once per month.  Is there a "fix"?

@TerryN10 -- this could be an "overheating" problem, where the motherboard detects the "over-temperature" and shuts down the computer, to prevent permanent damage.

Or, it could be:

* failing power-supply

* failing motherboard

* failing processor

If you restart your computer, and choose to launch the HP Hardware Diagnostics, do you get any error-messages?
