I was almost finished a game today and (not for the first time) the game just disconnected me, it still said I had my normal ping of 207 (aussie ping OP) and when i checked mobafire and lolking worked perfectly, then i reconnected for about 2 mins and it had severe lag, again with no ping issues or fps issues. It disconnected me again and then reconnnected me but it showed everyone being level 1, also it showed my farm as 104 (I was dc so dont abuse me for that) on the top right corner, but when I opened the scoreboard it showed my farm as 98, after the game ended it went black screen and said League of Legends client has stopped working and had the close window or wait to resolve problem thing, I'm not sure if the files I have for LoL are corrupted or something (the same thing happened 3 times in my last 10 matches) or whether my computer has something wrong with it.
If anyone has any ideas as to what is wrong please help
