[Crash] Game freezes mid match (Windows 10 Issue?)

Whenever I sit down and play multiple matches in a row, no matter what game type, eventually my game will completely lock up. Usually it happens in the third match or so I play and it locks the game so hard I cannot alt+F4, Ctrl+Alt+del or even Alt+tab. I have to end up soft resetting my computer when this happens.

usually it locks when I activate a skill, as I have never seen it lock up just walking down lane. It has done it in any type of match with any character.

I noticed it started happening shortly after I updated to Windows 10, and didn't notice it happening after any specific patch, as I switched Windows version and played on my old OS and new OS during the same patch, and it only started happening after updating my OS to Win 10.

Any help would be appreciated. I feel like I can't play knowing I'll end up bailing mid way through a match, and even logging back in takes almost 5 minutes to reboot :/
