i installed the NVIDIA GeForce Notebook Graphics Driver 301.42 update last night and this morning my living-room PC looked like this in 3D apps:

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 supsicious that it started exactly after teh update. how do i tell which one it is without spending money? what am i doing wrong??
