From: Compaq CQ1000CS Desktop PC Product Specifications


your computer has an external power-supply, but you've already verified the voltage & amperage being produced by that unit.


Product number: A0P02EA

Release date: 13-Jun-2011


So, the problem must be "inside" your computer. 

Most likely cause is a failed motherboard, which is very expensive to replace.


I tried:

but HP no longer offers to sell a replacement motherboard.


You might find one on eBay. Maybe.


But, since your computer is an "antique", it would be best to replace it.

It's likely that the current disk-drive, manufactured in 2011 (?) is likely to fail, sometime soon.

So, keep the disk-drive, and temporarily connect it as a "secondary" disk-drive in your "new" computer, to copy your personal files.


Note that Microsoft's support for Windows 7 will end in mid-January 2020, just 19 months away.

At that time, you will NEED to replace your computer.  So, replace it now, before your disk-drive fails.
