I originally tried using all the drivers from the Lenovo product page. This didn't help
They are missing chipset drivers entirely for win 10, so I had to get those from intels site.
When none of that worked, after everything else I tried, I went and updated all drivers to latest using driver booster. No luck.
In my opinion, this doesn't seem to be a driver problem. but at this point, anything is possible.
its an issue with TLS I'm pretty sure. just no idea the cause. This is unlike anything I've ever seen. But at this point, I've now spent way too much time on this problem. (1.5 days of my labor, along with my techs time who oroginally looked at the problem, and my partners time to double check that im not a crazy person) I'm about ready to throw in the towel. It's more of me being stubborn and wanting to find a solution, but im not sure one exists. Whatever I charge for this isn't enough, and I'm at the point where even if I did fix it, I'd be worried it comes back and i'd be on the hook for it again.
They'll likely need to replace the computer, and since I don't sell all in ones, will prob have to get that somewhere else unless I can convince them to go with a normal tower and monitor. (I hate all in ones with a passion, and this situation certainly isn't helping that cause)
