Thunderbolt ports stopped functioning

Hello,

First post in this forum, thank you for having me. I am not very computer savvy so bear with me. :)

I'm running

Windows 10 v 1809, build 17763.864.

I record audio into my laptop, into Pro Tools, through a Universal Audio Apollo Twin MkII. The Apollo uses Thunderbolt; my laptop has two Thunderbolt 3 ports, one powered the other not.

I don't know exactly when the thunderbolt ports stopped working, but it was in the last month. I recorded successfully using the Apollo in mid-October, and did not try again until yesterday, when I discovered the problem. The UA interface on my PC shows the unit as "offline."

I eliminated the cords as the problem by purchasing another. Same response. I uninstalled the Thunderbolt driver in Programs and Settings, then downloaded and reinstalled what I understand is the latest. I found that here:

I assume that I should see an item in Device Manager with the word "Thunderbolt" in it but there is none:



Any help would be greatly appreciated to get these ports back up and running. Of course I'm happy to provide more information. I can include PC information from Belarc or Sandra, or whatever works best.

Thank you,
Tim

Welcome to the forum. As your running an old version of windows have you thought to update to 1909 some changes can stop things working on older versions
