Hello, after the last big windows 10 update I have a black screen just after I am on the desktop. I have uninstalled the old driver (graphics card removed) and then the newest installed and the problem is the same ..
You may have caught the Windows update that contains a defective patch/hack for the Meltdown and Spectre vulns. Try reading up on this on a 2nd computer; also try connecting to the problem machine with RDC to see if you can pull another update. Finally, try booting into Recovery and backing out the update. HTH.
