Fps drop and no sound
I have a big in-game issue. My fps drop from 144 to 1 every like 2 second also I have no sound. The only solution I found was checking the "disable all sounds" in options which doesn't really help me much. I tried the hextech repair tool and even reinstalling it but nothing helped. It randomly started happened when I decided to play a ranked game, but worked perfectly fine a day before that. Anyone has the same problem or any advice for solutions?
