i have strange problem, here is all story:
About 3 months ago i bought new hardware (Motherboard, Proceson and RAM) just plug it in and run on existing Win 10 from old hardware configuration. Fortunately after bit longer first boot, everything was working perfect. So i left windows 10 for a moment and my computer was working perfectly. After about 2 months i decided to install windows 11 so i decided to do automatic upgrade.
In the begining everything seems to be ok but i found that from time to time my computer was shuting off by itself when i was doing USB related activities - (plug in, plug out, mouse move etc ) this was not repeatable but occured about 4 -5 times per week). There was not BSOD not anything just shut off like when somebody shut off the power. Also i found that one moment my mouse and keyboard was NOT working on a certain usb ports on MB in WIN 11 ( but were ok in BIOS). there were also some problems in device manager related to USB (yellow question marks) , after 3 days of fruitless fight ( i tried to do clear reinstallation win 11, bios updates , driver reinstallation , some other magic) i decided to go back to win 10 ( with a clean installation ) Problems are GONE usb devices works perfectly, did you ever have that kind of problems - related STRICKLY to win 11?
I have ROG Strix Z690-E With I9-12900K ,3090 Gaming Trio and 64 GB ram Bios 1720
