Windows 10: PC will not stay asleep/hibernated after upgrade

I just upgraded my PC with a new CPU, mobo, GPU, PSU, new NVMe SSD for my OS, and some various other doodads. My first time performing work this invasive on my own PC and I was pleasantly surprised everything booted up with no issues and I didn't burn my house down. Everything seems to be working great. However, my PC will no longer sleep or hibernate correctly. These items are enabled in my OS Windows 10, but as soon as it reaches the "asleep/hibernating" point of these, it immediately boots back up. Like, right away, not after a few seconds, or minutes, but as soon as the LEDs go off, it

PC Running Windows 10 Home Won't Stay Asleep/Hibernated

Since upgrading to Windows 10, my PC will not stay asleep for more than a couple minutes at most (in many cases, a matter of seconds). The PC refuses to go to sleep (or even turn off the monitor before that) on its own after the specified interval, even
with hybrid sleep off, multimedia set to allow sleep, and all other advanced power settings set to their maximum power-saving settings, so this issue is occurring in spite of deliberately telling the computer to go to sleep. The same is true for hibernation.

Using Windows 8.1 and the default "balanced" power plan settings, sleep had worked perfectly prior to the upgrade.
