When the computer boots, the power LED and decorative LED is coming on. I can hear the hard drive spinning up, and I can see the fan spinning on the processor. However, the fans on the video card are not spinning up, the gaming keyboard and mouse LEDs are not coming on. The video doesn't ever come up, even when I move the connection to the onboard DVI port. I am thinking that it either a faulty power supply, a faulty video card (didn't try completely removing it), or the motherboard has issues.
We tried to take it to Geek squad to have the power supply tested. They took it back for about 20 minutes then came back out and informed me that because the power supply is using proprietary connectors they couldn't actually test it. This was my computer, until about a month or so ago. I gave it to my son, since he was the one that used it the most. He moved it into his room and 2 weeks later it failed during a 10 minute hiatus while he was getting something to snack and and drink. When he returned the monitor was showing no signal and the lights on his gaming gear had gone out We followed all of the steps using the virtual assistant and were not able to resolve the issue.
Am I looking at just replacing the computer, or is there another course of action for a device that is 2 years out of warranty?

@snickers6910 -- is this your computer: HP Pavilion 690-0024 Gaming Desktop PC Product Specifications | HP® Customer Support
It seems to be a "standard" full-width desktop, and the web-page lists: Internal 400 W PSU
* 400 W SFF (Platinum) Full range 115V/230V
* 92% efficiency
I recommend that you take the computer to an owner/operator computer store, to see if that person can find a "generic" compatible power-supply, install it, and test it.
P.S. Note that Microsoft's support for Windows 10 will end in October 2025. At/before that time, you should purchase a new computer that will run Windows 11. So, don't spend too much money on your current computer.

That is the very one. I will have to check around the area to see if there are any qualified COMPTIA A+ certified people around. I would think that a simple voltmeter would confirm that all of the leads are providing the required voltage and current. The problem is finding out what the specs are on those expected values from each of the power leads.

Google knows all. Click: https://www.google.ca/search?q=computer+power+supply+pinout
to get many diagrams of the pin-out of the connector that goes to the motherboard.

I thank you for that information, but as previously stated Geek Squad informed me that the connectors were non-standard. So how would that translate to a generalized ATX power supply? I am not sure what connectors they were claiming were proprietary, but from the article you listed I can say for certain that the PCI Express connector and SATA connector are absolutely standard, not proprietary.
The PCIx ,connector is going to the GPU, and SATA to ...well you know, a SATA hard drive (2 actually, 1SSD and another 1TB platter). I am uncertain as to what connector is going to the motherboard though. Perhaps that is the one they were talking about though.

@snickers6910 -- one of the hyperlinks in the results of the search that I gave you is:
This page writes about HP's proprietary power-supply, and gives the voltages.
