Recently, while playing games my display has started become distorted, and weird patterns appear. It usually happens within a minute of use, sometimes earlier or later. It also randomly happens on my desktop, but not often. It seems like the display has gradually gotten worse since the problem started. I've tryed calling dell tech support but all they haven't been much help since not too many of them speak good english. This is what I have done to try and fix it: Connect to external monitor, reinstall operating system, delete and reinstall all drivers.
