PAVILLION ALL IN ONE WILL NOT START UP

PAVILLION ALL IN ONE
Microsoft Windows 10 (32-bit)

 I have a Pavilion All in one, 10 months out of warranty and out of the blue, the computer will not start up.  I am getting 3 long beeps, 4 short and a message re: unsupported adapter, and then it powers off. I have used the computer rarely, and this problem came up out of nowhere.  I have tried the suggestions listed here regarding the power cord to no avail.  Any other suggestions?  Looks like HP customer service will be hearing from me on Monday, as this is unacceptable.

@Donnabd Welcome to HP Community!

 

I understand that all in one will not start.

 

Please attempt the below steps: 

 

Attempt a BIOS recovery > All in one 

 

If the above steps work and the display turns on: Perform a hardware test to be on a safer side. 

 

If the steps didn't work, use the below links for further assistance:
