I am getting no video signal after doing the latest Windows updates, but it seems to affect something low level as restoring older images doesn't help.


Gigabyte Gaming G1 970

On Dec 9th was using the computer Windows update ran. Then had black screen "No signal found" Pressing ctrl+alt+del resulted in a dong sound from windows like an error message was up.
Rebooted computer ran fine for a few hours, same issue. This occurred a few more times with it becoming more frequent, until it occurred right after login every time.

Every time there was the following error: Windows 10 64 bit
Faulting application name: ShellExperienceHost.exe, version: 10.0.10240.16515, time stamp: 0x55fa599a

After a few more reboots it would start failing right when the Windows logo would appear. I could sit in BIOS or boot to my Macrium recovery partition and there would be no issues, or even the preboot Windows menu, only once Windows started actually booting.

Restored an incremental backup from before the Windows update. Still could not boot past the Windows logo.

Enabled onboard Intel graphics and allowed for multi monitor with it and was able to boot successfully.

Installed VNC viewer.

Switched back to GTX 970 was able to boot successfully, but had another no signal error shortly. Intel adapter and VNC both just black screen.

Switched from DVI cable to HDMI and tested additional monitor, same issue.

Next Day:

Booted to safe mode with networking on GTX 970 no problem.

Used DDU to fully uninstall Nvidia driver.

Was able to boot normally for about 30 minutes before I had another black screen.

Rebooted and was able to login, began Nvidia driver install. Driver failed to install, black screen
Was able to use VNC to still see desktop Device Manager showed GTX 970 greyed out and not detected. A few more reboots and the same thing, Was able to install latest Nvidia driver.

Reseated GPU. Was able to boot. Stayed up for 4 hours, put computer to sleep, woke up without issue and another 2 hours. Computer went to sleep again over night

Day 3:

Computer woke up fine, ran for about an hour. Black screen, no video on Intel or VNC.

Rebooted Shell experience host error returned, Windows updates had ran again.

Rebooted again, can't get past Windows logo.

Restored backup of Windows 7 from 10. Same issue, but was not a full reinstall.

Switched to Intel graphics. Booted to Windows 7.
Restored Windows 10 backup.
Can boot and stay up successfully as long as using Intel graphics.

I do not believe it is a hardware issue aside from when the card went missing and that was probably from me inserting and removing cables.
