I have updated from Windows 7 to "Windows 10 family" a few days ago. The installation was done without any error in about an 1 hour (including download time). After W10 installation, I re-install/upgraded all the specific drivers (mobo chipset, lan, sound, video...). I do not have any "?" devices. In short everything is looking fine.
But, since the upgrade to W10 at every cold boot (when I turn on the computer, it was not sleeping nor hibernating) I get an error in the Event Viewer: "Kernel Power - Even ID 41 - Task Category (63)". The event time stamp is the moment I boot. I do not have that message if I ask Windows to reboot. It does only happen when I turn on the computer.
The PC doesn't boot twice. It does boot in a few seconds (as it is supposed to do :) ) There is no pop-up message. Just the "error" in the event viewer.
I never experienced power issue with Windows 7. As far as I can tell, I never had a blue-screen, nor a brutal shut down. I never saw this message with Windows 7.
Since the installation, I did not use my pc much, but during the few hours it was on, there is nothing wrong. I did not launch any game. I stayed on the desktop (update Steam apps, Battle.net, drivers...)
My PC is fully patched, W10 is fully updated. I have the latest motherboard bios installed.
The PC Spec:
Asus Maximus Ranger VII
16 GB Crucial Balistix 1600 CL8 (2x8GB)
Crucial M550 256 GB (System - swap - temp)
Crucial M550 512 GB (Steam)
Seagate Barracuda 7200,14 2TB (stuff)
Asus Bluray reader
MSI Gforce GTX 970 Gaming
Seasonic M12-700 W
Nothing is overclocked. Ram are set (auto) to their XMP profile.
Any help is very much appriciated.
