Help my pc has power saving issues

[noobbuilder]

This is my old pc that i reinstalled windows 11 on and added a cheap used AMD card for my mother.

 

Problem 1:  no matter what setting in power saving i choose or change the pc still goes to sleep after idling for some time.

Problem 2. no matter what setting in power saving or device managers usb properties will allow any usb device wake pc

problem3. Pc stays on fine if shes watching netflix or youtube, but if she puts on spotify after 3-5min the tv says no signal.

 

The only hardware changed was the gpu and the ssd.

 

Any ideas and i have zero experience with amd cards or their software, but this is the third pc i have built and never had any issues like this ?

 

pc specs:

new install w11 home

used amd 580

i7 8700

32gb ram

msi z370

Just a hunch but maybe try staying on win10, i've ran into a lot of issues with win11 on older hardware (AMD CPUs and GPUs) on PCs and Laptops i have worked on...

Win 10 in majority of cases helped solved the issue or even fixed it by itself...
