Everytime I start my pc up it this pop sound just happens and its kinda annoying me now. Also this weird buzzing sound occurs when I start it up after a couple of seconds. I have one more thing, sometimes when i launch up roblox and tab out my pc screen turns black and this really loud buzzing happens. any help?
