Every game 0 fps around 8-10 min mark

So this crap keeps happening to me every game since after Sylas was released, so patch 9.2 or something then next patch 9.3 i had this bug where game just drops to 0 fps from 120 for like 30-40 sec and then unfreeze and lags on 10-20 fps for next 30 sec and then back to working normal rest of the game. This happens every 2 patches so next patch 9.4 i didn't have this bug then patch 9.5 and bug is back its going like that even now on 9.11 patch,didn't have this on 9.10 i tried everything to fix,repair every day,reinstall game like every week,i don't even know what happens around 10 min to make game freeze like that only thing i can do is wait for next patch..... {{sticker:sg-soraka}} {{sticker:sg-soraka}} {{sticker:sg-soraka}}
