So I came home today and my kids were having issues with our family pc. After some looking through device manager, I saw that, while there was a driver installed, when I click on the "Driver Details" box, I get a box telling me that "No driver files are required or have been loaded for this device". That makes no sense to me because I clearly installed the driver and the resolution changes to the correct resolution and everything. The biggest problem with all of this is that when I restart the pc or try to log in with a different account on the pc, the resolution goes back to, well, bad, and I have to go through the whole issue of reattaching the driver, but it is not permanent. I'm running Windows 10 64-bit, and I have 2 AMD Radeon HD 6900 cards installed.
Update: I just went into the AMD Radeon Settings software and it doesn't even show the two cards. It shows the integrated graphics, but not the two addon cards that I have crossfired.
