[CRASHES] Everytime I load into a game, my PC crashes and it kicks my GC fan into a frenzy...

So every time I get fully loaded in I hear the loading sounds, sometimes it lets me buy items, then my screens go black, and I can hear sound but I have to restart my PC and it counts as a leave. I don't want to get banned for this and am already in low priority queue because of it....

I have an omen 880 with a 1080, 16gb RAM, i7, etc...and my PC plays all my other games fine. My league was working yesterday morning, and this started last night.

I played 2 games last night fine, but have crashed on 4 load in so far. I just changed my settings to compatibility mode for windows 8 even though I'm running on windows 10. I don't know if this was the fall creator update I just did or what it is, but I'm trying to solve it best I can and don't want to get banned if this keeps happening when I load in.

Update: It's letting me use the practice tool without crashing, I'll try to play a game now... :/

Update: So I played a game fine, so this might be a fix, still doesn't fix my queue times but whatever I guess, hopefully people can find this if they have the same issue.
