System doesn't turn off when I shut down

[Minibiker]

Hi all

I bought a new GPU yesterday (second hand), Fitted and tested, all works fine and performing great. The issue I've come across is the fact my PC doesn't turn off when I shut down, it just keeps the fans spinning on CPU and Case fans?!

Anybody have an idea of what can be causing this?

Thanks

Have you tried DDU to clean uninstall of previous driver, especially if switched manufacturer. Other thing to check if there is a system process that is altering performance profile under power management.

Sounds like driver conflicts. Or a dodgy GPU. Try the GPU in a different slot maybe?

Does it do this in safe mode? Also if you have spare USB pen drive, stick any distribution of Linux on it and boot to a live environment (no install required) then try shutting the PC down using the Linux task bar.

If the issue persists then its hardware but if not most likely Windows is the culprit.

Is it staying off when you hold the power button?

Yes, when it comes to turning off I need to hold the power button, I will try the above later and hopefully it will resolve it

Control Panel\Hardware and Sound\Power Options\System Settings
had a look at this?
how is power button configured?

Disable fast startup

Hi all,

So I've had a look at the above possibilities and the pc still doesn't turn off when I shut down, fans stay spinning and CPU heatsink still spinning?

I must be missing something in a setting somewhere

Have you tried removing the motherboard battery,and then pressing the power button several times (unplugged)? Then leave it for a minute before booting back up. It might just be a fresh windows install could fix it. Don't quote me on that though, it's just a suggestion.

Had the same problem last year. Turned out it was an expansion card which didnt liked my 7900XTX.

So you reckon something conflicting with the GPU?

What PSU have you got and how old is it?

Does your new GPU need more power than the old?

As coincidental as it may be, I'd try a different PSU if possible.



Also a huge amount of suggestions here for a B450 M Aorus if you haven't already seen it:

I don't know, from my experience it was another piece of hardware causing the problem.
