Windows 11 with latest patches boots to blank screen with no login or cursor. I have 3900x and nvidia 1660 super. Had to revert back to amd chipset driver 3.10 from Gigabyte site for my B550AX board....

F15 released for B550 Aorus Pro CV
AMD over the weekend reportedly released the AGESA V2 PI 1.2.0.7 microcode to motherboard vendors and PC OEMs. This particular version of AGESA gains importance to those on Windows 11, as it corrects a performance-stuttering issue caused due to frequent polling...

I would try replacing the motherboard battery to see if the issue goes away.

New AMD chipset driver.

I have external storage drive connected to the front and the mouse and keyboard transceivers connected to back USB 2 As for bluetooth it just refuses to connect with my phone even though both shows its paired. I am unable to do any send receive of files.

I had to do that as the dreaded keyboard stutter appears with all of them if connected to USB 2. Sadly bluetooth still doesn't work with latest Intel drivers on Windows 10 21H1. Works on Linux though but slow....

Flashed 13G on my Aorus Pro AC Wifi motherboard but unfortunately the dreaded keyboard stutter comes back unless its connected to USB 2 port, also standby tends to hang, back to F12 for now.

I downloaded version 10.50 LAN from station-drivers and its running fine here on the B550 Pro AC AORUS.

The irony being the BT and LAN issue doesn't plague linux installations using latest kernel but sadly even with Windows 10 21H1 and with latest intel drivers the BT disconnects frequently on Gigabyte AORUS Pro AC with bios F12, tried 13j but my keyboard stutters badly when connected with usb 2.0 port....

Am on the latest Windows 10 update but I have F12 so no issues yet....
