I installed teh NVIDIA GeForce GTX 980M/GTX 970M Graphics Driver 344.24 update last night and this morning my gaming desktop looked like this on the desktop:

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 because 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? thx in advance!!
