This has started happening very recently, in all of the Source games that I have tried to run, they completely crash my computer. For example, when I first load into a save in Half-Life 2, my screens go completely blank and the sound that was playing gets repeated over and over until I hard shut down my computer. This has also happened with CSGO and Garry's Mod. I downgraded my driver from 17.1.2 to 16.7.3 and it stopped crashing.
