not gonna lie this is driving me nuts i installed the Gigabyte Intel 915G VGA Driver 14.8.0.3929 update last night and this morning my living-room PC looked like this in the 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?
