Thanks for your suggestions.
I installed the Intel Driver & Support Assistant but it didn't find any supported Intel drivers.
The ASUS supported drivers are only for windows 7 and 8. I could grab 8 drivers and see if they're fine with Windows 10 I suppose.
Here's a link to the ASUS driver page for my machine:

Reinstalling back to windows 7, the original software, is something I wouldn't relish doing. Windows 7 end of life was January of this year, so its no longer supported and will not get security updates. I would probably have to then update to windows 8 at the least and try that.
Is there any GPU testing software that will just run a bunch of stuff to tell you if my card is the issue?
