Hi! I'm sorry if this is stupid I'm completely unexperienced with pcs. I downloaded a recent INTEL graphics driver as reccomended and I don't believe it was completely compatible. (I believe it was the Intel® Iris® Xe Graphics i downloaded, but the driver was called intel UHD 770.)

My screen would go black, it told me a shortcut for a gaming overlay which would also make it go black. Trying to uninstall the driver made it go black and I couldn't roll it back to I disabled it. This also made it go black.

Turning my pc itself and checking my cords hasn't worked, my monitor itself is fine but says no signal. Have I done something really dumb?
