Game Crashes After Entering A Match

So I about a few days ago my computer updated to I believe a new version of windows and now every time I am launched into a game I crash. I can't do anything but **hard reset **since nothing works and there is a sound loop that is really annoying when it freezes like that. The problem is I haven't even started to move from the fountain when it crashes so then I am forced to leave the game and have it be remade. Then I get really tilted because not only do I lose lp but I also get leaver buster. Please someone help me
