Windows 10 Anniversary Update & MOBAs

I switched over to the new Windows 10 update a couple weeks back, and felt fine doing it since my laptop was listed as being tested for the new update.

Everything was fine until I noticed that I couldn't play any MOBAs. Dota 2 and LoL both completely freeze my laptop any time they load the main screen. Once they freeze, there is nothing I can do, no ctrl+alt+delete, no nothing. I just have to hard reset the computer. Every other game runs just fine, so I don't know what the problem is or how to fix it. Any help would be much appreciated.

I have an Inspiron 5558 and all of the drivers are up to date with what Dell has on their website.
