NUC8i7HVK with eGPU doesn't show login screen after the first boot

[Lakrimosa]

Hi,

I have an Intel NUC Hades Canyon NUC8i7HVK with a connected eGPU by Razer (Core X Chroma).

The eGPU contains a Nvidia GTX 1080Ti and is connected with a Thunderbolt cable which came with the eGPU. My two 28" monitors are connected to the eGPU with Display Port cables.

I never get the Win10 login screen displayed after I start the NUC for the first time at the day.

The NUC has bootet and the USB devices (mouse and keyboard) are connected - I can even hear the connecting sound, but the monitores are still dark.

I always have to push the power button until the NUC is switched off. Then I turn it on again and I got my Win10 login screen.

I don't have this problem, if I connect the two monitors directly to the NUC.

Windows 10 is installed and up to date. Every driver is installed and up to date.

Windows 10 Pro - 1903 - 18362.175

I have installed the App Thunderbolt Control Center from Microsoft Store. In the App the Razer Core X Chroma is set to "always connect".

What else can I do to get the login screen displayed normaly?

Thanks in advanced.

Edit: Windows 10 version added

Have you updated the nuc bios?

Have you updated the nuc thunderbolt? https://downloadcenter.intel.com/download/28735?product=126143

Have you checked with the manufacturer of the eGPU?

What version of windows 10 are you running? 1903?

The Thunderbolt driver was up to date, already.

I just updated the BIOS, but it didn't solve the problem.

My Windows 10 Version: Windows 10 Pro - 1903 - 18362.175 - Windows updates says, that it has nothing newer.

I didn't contact the manufactor (Razer) of the eGPU, because the eGPU works fine with a friends notebook.

I tried the described steps, but I can't install the Thunderbolt 3 Controller Firmware Update Tool, because of an error message.

Error: 0x208 SDK_SERVICE_NOT_FOUND Thunderbolt (TM)

service doesn't exist

My eGPU is still connected and running and I can use it (it has USB 3 slots, which are working, too).

I bought an Displayport switch 2>1 (2 devices to 1 monitor) and I connected the monitor I am using for games to that switch.

When I work, I have both monitors connected to the NUC and if I want to play a game, I press a button on the remote control from the switch and the gaming monitor is connected with the eGPU.

That works fine for me.

The error "0x208 SDK_SERVICE_NOT_FOUND Thunderbolt(TM) service doesn't exist" occurs when the Thunderbolt Bus Driver for your Intel® NUC is not installed.

Hi Wanna!

I am getting the exact same error, but the Bus Driver is installed. I already uninstalled and installed it again several times. No luck to start the firmware update tool.

Also all drivers are up to date according to the intel driver and support assistant.
