High CPU usage & DRIVER_POWER_STATE_FAILURE
Hello!
I am having really nasty problem with my Windows 10 install. I recently bought and build new setup, installed Windows 10, and everything worked just fin... until it stopped. After some time I noticed I have high CPU consumption by ntoskrn.exe. I googled it and found that I probably need to update my GPU drivers - but AMD does not support older architecture, and I already have newest available drivers installed (15.7.1). So I updated all other divers for motherboard etc. It did not help.
The strange thing is that sometimes when I log in it works just fin, and another time CPU usage of ntoskrn.exe ramps up as soon as I log in. Sometimes it starts after waking from sleep or hibernation.
Few other things:
- when this happens I cannot install or uninstall any drivers, I cannot even go to drivers details tab in Device manager (it stucks).
- I cannot run several programs like SpeedFan - I think because they need elevated permissions
- sometimes it just BSODs - "DRIVER_POWER_STATE_FAILURE"
- I cannot put it to sleep, turn of, hibernate - simply I cannot sjut it down properly. When I try to it "hangs" on "Shutting down" and after few minutes turns off. After powering it on again I clearly see that its a fresh boot, not waking form hibernation. I saw few times same BSOD as above - other times my screen just turns off so I cannot confirm if this happens every time, bu I assume it does.
I really need some help, because I'm out of my mind right now. It is very frustrating and I do not have any idea what causes it. I assume it is some driver failure, but which?
Thank you in advance.
