League Client Closing/Crashing

My Client for League has been closing and/or crashing for the past few months with most having Lolclient.exe(or something) saying something has went wrong and needs to close program, and a quite a few times having it just close for no reason without giving a reason such as the little pop-up windows... I've checked all my game files with none of them being corrupted(just in case I have Deleted each one and uninstalled and re-installed a few times) I've checked my internet(SuddenLink) and nothing is wrong with their end So i thought it might be my end so i check my computer in and out(Figuratively and literally) also my router and modem and nothing

Can anyone tell me whats going on? Is it Ritos fault or what? If so, I demand my LP back since this has happened in champ select and in game which has lost me quite a bit of games/LP and possibly have gotten reports for AFK
