Lately (past 1-2 months), I've been having these issues with my Intel Graphics. Graphics drivers would stop responding and then recover. Seems to happen with Source games, mostly CS:S and GMod. Crashes mostly when opening a game. Some weird witchcraft going on with the Win10 start menu (see video below). Changing colors/transparency doesn't fix it. Monitor doesn't wake up after moving mouse/keyboard (used to work). "Turn off the display" in the power options. I have to manually turn off and on the monitor for it to detect. I've tried installing latest 4thGen Intel drivers from the Intel website, drivers from Win10 Updates, and completely removing all Intel software/driver and reinstall from MSI (my mobo). And yes I've restarted my PC plenty of times. You guys will probably say get a graphics card... I "might" get one soon.

Don't use intel graphics. Problem solved. In all seriousness the easiest way, though not the most economically efficient, might just be to buy a cheap graphics card that isn't integrated Intel bullshit, lol.
from what I have heard, Windows 10 doesn't/finds hard to play VALVE games. What I think is the problem is Operating System rather then Graphic Drive itself. PS - like Mapple said upgrade your graphic to better ones, I personally recommend Nvidia Geforce.
