[CRASH] Game is crashing pretty much everywhere

So, I've just been having like 3 of the worst days in league. My client keeps crashing pretty much everywhere. It crashed during champselect, loading screen, ingame, etc. In champselect the PVP.Net client or something crashed, and basically the whole thing froze, and I was kicked out and lost LP+ time penalty, twice. That was on my NE account. Logged onto the West one, and worked nicely. I've also been getting this DirectX related error, and whenever I go into the loading screen, it pops up, and my game crashes, and I'm back to the reconnect screen. I have quite a decent computer, which can handle league quite well, with all drivers right up to date, and everything is in working order, with the latest Directx11 installed. Please help? I've attached some screenshots that I've been able to take. Thank you in advance, and wish you the best of luck on the rift.
