My HP pavilion desktop 400-434 will occasionally just power off and won't start back up until I've left it unplugged for a significant amount of time. Talking hours here.
Nothing brings it back unless it's simply unplugged for hours.
My guess is "overheating" has caused the motherboard to shut-down the computer, to prevent permanent damage.
Letting it cool-down for a few hours seems to be a good idea.
Google-search for "download free SPECCY".
Download, install, and run SPECCY, to get it to report:
* temperature of the motherboard,
* temperature of the processor,
* temperature of the disk-drive
Run SPECCY when the computer is "cold", to get "baseline" numbers.
Run it every 20 minutes, to see how the numbers change, as you use the computer.

The motherboard only reached a sustained temp of 106 for about an hour. But once I plugged something into the USB the load seemed to kill it. I'm starting to suspect that maybe I just simply have a couple of compromised power supplies that may have been degraded by my house power. Either that or something with the motherboard can no longer handle the load.
Any other ideas?

What the wattage of each of the power-supplies?
Have you added-in a high-end graphics card? An extra fan? An extra HDD ?
What device(s) are connected to USB ports?
Are you using a "powered" USB hub, in order to draw less power through the computer's USB ports?
Are you plugging some USB devices into the USB 2 ports, and some into the USB 3 ports?

Can you purchase a UPS (Uninterruptible Power Supply) to locate between the wall-outlet and the computer, to provide "smooth" power to the computer?
