hmmmm ok i installed teh NVIDIA GeForce Graphics Driver 390.77 update last night and this morning my gaming desktop looked like this in teh browser:

little colored blocks, flickering lines, sometimes a whole strip of the screen goes green for a moment. it doesnt crash, it just looks horrible... my stomach dropped cuz artifacts usually mean dying hardware, right? but its suspicious that it started exactly after the update... how do I tell which one it is without spending money? seriously need help here 😭
