Elitebook 840 Graphics Issues after Win10 Upgrade

[840G2User]

I recently upgraded my Elitebook 840 G2 from Windows 7 (64 bit) to Windows 10 (64 bit).  After upgrading, I get Code 43 errors in Device Manager referencing the Intel 5500 graphics driver. Everything else seems to be working, but I'm stuck with the generic Microsoft driver and cannot sense or drive external monitors. 

I've updated to the latest drivers from the HP site after it correctly detected that I was running Win10 (64). I'm on the latest BIOS. I've even tried to manually install and run drivers for this graphics unit from the Intel site with no luck. I can't downgrade to Win7 so I'm stuck.

When I mentioned that I had tried to install the Intel drivers, those were the drivers I had tried. Thanks for attempting to help though. I'm really disappointed that the drivers HP provides for Windows 10 don't seem to work. Perhaps they did at one point and were subsequently broken by a Windows 10 update. I would hope that HP would update their drivers as well. Even if I could go back to an older Windows 10 state, I'd have to somehow keep it there and it kind of defeats the purpose to upgrade from Windows 7 which is no longer supported.
