Thanks for the reply Joshua, but I've already tried that download unsuccessfully.
When trying to load the graphics drivers, an error pops up saying that "This installation package is not supported by this processor type."
It seems as though that download does not apply to the i7-8559U processor.
Are there any other places that might have the correct driver?
There used to be a response from an Intel employee suggesting I update my Windows 10 to the latest from Microsoft.
That was the issue. After updating Windows, I was able to install the graphics drivers without issue.
I went to the Microsoft website and downloaded the Windows 10 Update tool, and used that to bring my version of Windows 10 up to date. Then I installed the graphics drivers that were suggested on the Intel website.
Thanks to those that helped.
