[CRASH] Random Crashes with any champion.

So for about roughly several months(3-6 total, on going still) or longer I'd say randomly crashing without a pattern. It happens once per a match then runs smooth through and through without any further problems. I've tried a majority of solutions CCleaner (Piriform), Repairing my files on the launcher - came out with 20k scanned, I've tried multiple methods and fixes, noone have worked so far. This is strange and I've been just this week has gotten worse and i've gotten 2 leavebuster low priority queue's in a row and I am not sure what is causing it. It is random it and not based on the fact of team fights too many things going on spells and stuff. I'm not certain but it sometimes comes out still as 00000x0014 Referenced memory error, I've seen this solution use CCleaner but that doesn't work or cut it apperently. I still see it time to time when I Crash. I sometimes get BugSplat and when I submit it just gives me the same old solutions that don't work for me. If this helps, or solution at hinting what it might be. Before this problem started, I had my launcher on adminstraitor due to it wouldn't launch sometimes, after months that fixed it and I unchecked it and this is now what happens instead of my launcher not working at all. I'm literally out of ideas, solutions and completely brain drained at this point. I'd take anything to try or use. I hope I don't have to see trolls make jokes. The champs I'd like to mention I use regularly and often that I don't think make a difference since it crashes on each, Lux, Ahri, Zed, Lulu, Katarina, thats about it. I don't think or I am not aware if my security I use would interefere, but I have AVG if that's applicable. I lastly submitted a bug report at least once this month or long ago due to I don't want to have a history of spamming this same problem. There is no pattern is why I don't report it because I feel like it'll be only ignored more often seeing me as a pest or problem and just deleting or pushing it off to the side is why. I'm not sure where to find my logs and extra crap in my folder in time for uploading to bugsplat because I don't want to delay time and it takes me 6 mintues to relaunch into a game after I crash, and 5 minutes isn't enough time so I obviously everytime get a leavebuster queue very easily because of 1 minute short and also I care to help my team always and this crashing is extremely irratating at times as you would imagine espicially in early games/late. The items I don't think have anything to do with my problems but these are the ones I use usually in games on my champs I'm completely bummed and I'm not sure if Leavebuster low priority queue can actual lead to a suspension or ban. If there is a solution found, I'd be incredible thankful and extremely happy. As well as I can take the option if someone does recommend me to reinstall the game, if necessary by all means.
