Windows 10 Pro boots to a black screen.
I have a number of Lenovo PC’s that have been having an issues where the system slows down. After restarting the PC the PC will boot to a black screen. CTRL-ALT-DEL does nothing, nor does CTRL-SHIFT-ESC. The caps locks does respond. We where able to get one PC to show a display after pressing CTRL-WINDOWS-SHIFT-B but only once on one PC. You do see a lot of disk activity but that is it. If you attempt to boot into safemode the system appears to hang at the Lenovo splash screen. The only way to fix the PC is to perform a system restore. We have made sure that the BIOS is at the latest level. I am unsure how to troubleshoot this further. Any ideas would be great.
