I have an Nvidia RTX 2070 in a Razer Core V2 over Thunderbolt 3 to my Dell XPS 13. 

When I plug in my laptop to the eGPU, it fails to connect. The graphics card shows up in the Device Manager with a yellow exclamation point: "(Code 31) Insufficient system resources exist to complete the API.".

Disabling and re-enabling the device doesn't work. Power cycling the eGPU does not work. Unplugging and re-plugging does not work. The only thing that fixes it is rebooting the computer. But that only fixes it once. The next time I'll have to reboot again. I'm tired of losing my work and I can't find anything online about this error that works for me.

I have used Dell Command and SupportAssist to make sure all my drivers are up to date. Windows update is up to date.

I have run the following commands in addition to everything on http://decentsecurity.com/holiday-tasks to make sure everything is running smoothly.

Sfc /Scannow 
Dism.exe /Online /Cleanup-Image /StartComponentCleanup
Dism.exe /Online /Cleanup-Image /RestoreHealth
fsutil resource setautoreset true C:

Any additional debugging ideas? Thank you!
