My computer shuts down to a strange state of stand-by

Hello. I'm not really sure what causes this, but whenever I shut down my PC, it goes to a weird stand-by mode. What I mean by that is every USB device is still running. A diode on my MOBO labeled 'stand-by' is lit. So far, I have three suspects - new PSU (Seasonic G-series 500W), new chassis (Silentium PC Gladius M20 Pure Black), or Win10's Fall Update. I'm pretty sure that stand-by thing started happening after I replaced my chassis. Can it be that I connected the power button in the wrong way? Or if it is the PSU, does it mean it's broken? I'm rather helpless when it comes to hardware, so I'd appreciate every little bit of help. Thank you in advance! :)

EDIT: I forgot to mention something probably crucial. The task manager keeps counting "Up time" even after I supposedly shut down my PC. That's what bothers me the most. That the computer consumes electricity all the time.

Hello, rzepek2pl. Welcome to Windows TenForums.

Exactly, that's my mobo.

Nor sure about the hardware myself other than making sure you followed the schematics and instructions upon assembly. You may want to double check if you have not already.

On the system software side you might want to read through your manual and perhaps this: Sleep States Available on your Windows 10 PC Performance Maintenance Tutorials

Nice MoBo, BTW. :)

I actually did think about turning off the Fast Startup but I rejected that thought because it was on before I bought both the PSU and the chassis. On the other hand, since my system boots from an SSD in 10 seconds, I can give it a shot. I won't mind a little slower startup. I'm not home right now, but when I am, I'll check it out, as well as the USB selective suspend. Thank you! :)

I'll check my PC sleep state when I'm home. I just skimmed through that post so I still don't know how to change the sleep state. I'll be worrying when I check it, though. Thank you! :)

Hi rzepek2pl, and welcome to the forums. You may see if selected suspend is on or off in Advanced power settings. You can also check what the power buttons do there as well. Turn On or Off USB Selective Suspend in Windows 10 Performance Maintenance Tutorials

Another thing you could try is disable Fast Startup, which causes shutdown to actually go into a deep state of hibernation instead of completely off.

Unfortunately, none of your hints helped.

I checked my sleep state, but I still don't know what to do about it. :/

What is your ACPI state? Try setting that to one that works via the tutorial I linked. Please notice that there are more tutes at the end of that one.
