I'm experiencing this bug already for months and I can't figure out what's causing it. Before I show you, I need to say that this bug usually happens after inactivity. For example, if I'm done doing things in my computer and leave it for a few minutes or hours and then come back to to it, this is when it happens. Here's the video of it. As you see, I can't do anything and if I click the mouse, computer beeps like that and it lasts for a few seconds, sometimes almost a minute, then it goes back to normal. Anyone knows how to fix this annoying glitch?
