My computer was working fine on Steam when suddenly the screen dimmed, resolution jumped to 175%, and now everything's slow. I ran an antivirus scan but found nothing. Could this be a faulty Windows update? If so, how do I reverse it?

Hi, I am Dave, I will help you with this.
The best option is to completely remove the current graphics card device driver using the widely available free DDU utility, then restart your PC and go to the support page for your PC on the manufacturer's website to download and install their recommended version of the graphics card device driver.
A slightly older version of that driver is more stable than the latest version.
