SOLVED -   - Extracted the UHD Intel Driver exe to desktop   - Switched from Basic Display driver to Intel display driver (device manager)   - Quickly deleted the Intel driver in Device Manager (seemed to have to be enabled first before it could be deleted) - restart laptop - open device manager and select to update the display driver  - manually select the folder you previously extracted on desktop Hope this helps someone. 
I recently did a clean install onto my Latitude 7480 (two actually). The first one through using the Media Creation Tool and directly creating a bootable USB and after experiencing the system/screen freezing I did clean install again a day later but this time downloading the ISO (using the tool) and then using Rufus to make a bootable USB. Was hoping that this re-installation would solve my issue but it has not.  I'm quite certain the fault is with the intel graphics driver. I booted to a linux USB and used the laptop like that for 2+ hours without any issues. In Windows, as long as I run the "Microsoft Basic Display Adapter" the system does not freeze. I have used it like this for over 10 hours with no freezing. Usually within 5 minutes of updating the driver (through device manager interface) the system will freeze. The longest I have left the system frozen is about 10 minutes. Nothing. Everytime it freezes I have to force shutdown. I have tried enabling the Intel driver many times and each time it freezes in <5 minutes so I'm nearly certain that's the issue.  Things I have tried: - clean install of Windows 10  - Going to Dell Support and running the Dell automatic driver update utility - manually downloading ALL my system drivers on the Dell website and installing them one by one - bios update - system is fully updated through Windows settings updates None of the above has worked. Here is the odd part:  The display driver that is available through the Dell support page for my laptop WILL NOT INSTALL. When I try to install it I get the error "this operating system is not supported". I also tried installing previous versions of the Intel driver and the same error occured.  Any help is greatly appreciated. Totally at a loss here now! Last question: what is the best way to attach my install log to this post?  Thanks!
