When sharing a troubleshooting thread, it's important to provide detailed system specifications. List them clearly as follows:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Include the age of the PSU along with its make and model, and the current BIOS version for your motherboard.

Like I said it's a store bought Cyberpower tower but here is what Windows says:
CPU Intel i7-8700
MB Asus Prime b360m-a
Ram 32
GPU Nvidia 1060
Windows 10 Home
Monitor Asus
PSU generic
SSD generic
I did this: To stop your Windows 10 computer from automatically restarting on errors, go to your Control Panel, navigate to System and Security > System > Advanced system settings, then under Startup and Recovery, uncheck the "Automatically restart" option in the System Failure section.
However, I used eventvwer.msc and got this critical error but there are no codes:
Critical: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. I have the computer on battery backup so it didn't lose power.
I do have two other errors also, but they are not critical.

Is this a fresh problem or something they've handled before? When was your purchase of this PC? The PSU model is important. Remove the side panel to check its contents.

Wow, it has a label! It's a thermaltake 600 W PSU. It began about six months ago but hasn't been used much. It worked two times this month, though not consistently. I purchased the PC as a backup in 2019 and only opened the box in 2023. My concern is whether dust might cause it to restart. Right now I can't clean it because of snow and ice outside. When I opened the side panel, there was a bit of dust visible.

These random restarts are often caused by the PSU. The PC is shutting down due to power loss. The changes you made were related to gettings errors, not a sudden power failure as I believe is happening.
