Garrys Mod Wont Open

Ever Scince i put the option open in a window garrys mod wont open. I uninstalled the entire thing and its still not working. It will open for a split second in a window and then close all of a sudden? Anybody know how to fix the problem?

Well, what’s your desktop resolution?

Put it higher, to something greater than your gmod resolution :slight_smile:

Right click Gmod, click Properties, Set Launch Options, type “-fullscreen”
