Computer wont power down properly

[16bitbarkeep]

hi folks. been trying to figure this out for a while now. my desktop seems to be running fine. however when i choose to shut down via the menu power options, it wont completely shut down. monitors shut down and then the RGB lights and fans run continuously. only way ive gotten it to power down is using the power button. this also effects sleep mode. it'll go to sleep but i wont' be able to wake the computer without hard powering down and restarting it. ran mcafee  no viruses present, and my warranty is up. any thoughts? thanks again

IT could be a feature of Windows 10 known as Fast Startup -- as that will force the PC into hibernation and prevent it from completely shutting down.

Win10 has enabled a new hibernation process known as Fast Startup -- which is enabled BY DEFAULT. This is different from Fast Boot, which is a BIOS/UEFI option.

Fast Startup is supposed to dramatically speed up the booting process, but in some PCs, it actually slows it down or causes it to hang. It's also a new form of hibernation known as hybrid sleep -- and this causes battery drain to maintain the state of the PC while turned off. In some rare cases, it can also cause a laptop to overheat because the processor is still running and still generating heat, as this has been reported when the laptop was turned off and put inside a case.

Disabling Fast Startup might fix booting and shutdown problems.

There are two ways to disable FastStartup in Win10: (1) through the Control Panel, and (2) through an elevated command prompt.

Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup

Elevated command prompt - run the following command:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F

In both cases, reboot Windows.

NOW, Fast Startup is disabled.

See if that helps.
