Dell XPS 13 9350 Intel graphics update prevents bootup

[RBroo1]

Approximately 10 days ago, Dell pushed a bios and Intel graphics driver update. My wife accepted and after downloads, she hit Finish and Restart. All she got was a blank screen. No way to get to Windows 10 Home.

The built-in Dell utilities went through various tests and found no hardware problems. Eventually, I got the machine to a command prompt, reset Windows to boot in Safe Mode, and that did boot. In Windows safe mode, as suggested by someone on Tenforums.com, I disabled the Intel graphics driver. When I rebooted, Windows ran almost normally. Functions like sleep and standby were disabled. Some popup screens were showing up with tiny type, something I had been able to correct when the Intel graphics was running.

Thinking that maybe the Intel update hadn't gone through correctly, when Dell again pushed an Intel update, I accepted it. This time when it wouldn't boot, it was worse. Again with advice from Tenforums,com, I disabled Intel virtualization and VT in the Bios. From there, I was able to go through the Safe Mode and disable the new Intel driver.

I then did a System Restore. I think it went back to right before the updates but I had not been keeping track of Intel graphics driver version numbers. In any case, right now the machine has Intel Iris 540, 4/21/2017, v. 21.20.16.4664 showing in Device Manager. It has to be disabled for the machine to boot.

The long version of this story is https://www.tenforums.com/general-support/115040-bizarre-boot-failure-dell-xps-13-no-error-msgs-4.html# post1429263http:// here.

So, does anyone have an idea of what could be causing this and what a fix might be?
