@lauriej, welcome to the forum.

 

It may be the motherboard, but before we make that determination, let's try some things to make certain.  Most motherboard failures are due to failed capacitors.  Here is a guide that will help you.  Here is a picture of a bulging capacitor:

If they look like the two with the red arrows, they have failed.

 

If all of the capacitors are good, then, you should test the power supply unit (PSU).  Here is a guide to help you troubleshoot it.  Once you have checked these two items, if they don't appear to be the problem, let me know.

Thank you for the additional information, @lauriej.

 

Absolutely, if your husband is capable of replacing the capacitors, he should do it.  If it is not the capacitors, you should test the memory.  It can cause the symptoms, also.

The problem that you will have with replacing the motherboard is, HP motherboards are tatooed with the major components of the computer.  Therefore, you won't be able to use the Recovery media.  This means buying a full operating system.  HP has their motherboards made to their specifications.  It is difficult to find a motherboard that has holes that will fit the stand-offs in the case.  If you find a board that you like, you should contact the manufacturer's Tech Support to see if they can tell you if it will work in your case.  Another problem can be that the connectors for the Power Button may not be the same.
