Sorry, I can't give too many system details because, well...black screen. But it's an HP small form factor desktop with a Core2Duo processor running Windows 10. I was in the Catalyst Control Center adjusting the display resolution, and when I hit "Apply," the screen went black. Now, whenever I reboot, I get the Windows logo, but as soon as it loads the graphics driver and goes to the lock screen, it goes back to black. Only solution I can think of is to abandon the use of the AMD graphics card, and I kinda don't want to do that.
