Question How to find the cause of my pre-built computer restarting...

[hayley3]

I turned off the restart but the computer STILL restarts and doesn't give me an error code. TIA for any help!

Thanks,
Cheryl

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

I turned off the restart but the computer STILL restarts and doesn't give me an error code.
Please elaborate on this.

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 new issue, or has it done this for a while?
How long ago did you buy this PC?

PSU make/model is critical.
Take the side panel off and see what it is.

Oh wow, it does have a label! It's a thermaltake 600 W psu.
And it started about 6 months ago but did it rarely. It's done it 2 times this month. It's not constant though. I bought the PC as a backup, so I bought it in 2019 but opened the box in 2023. ETA: I"m wondering if dust could make it restart. I can't clean it right now, we have snow and ice outside and When I opened the side panel, it is a little dusty over there.

Random restarts like this are usually due to the PSU. The PC is restarting because it is losing power. Those settings you changed were for gettings errors not sudden loss of power like I suspect is going on
