Hello, i have a HP Pavilion 14 with windows 10. Intel i7-4510U, 4GB RAM, NVIDIA 840M. I dont know how and why but my pc is so laggy and start to make a crackling sound like a sound of a bee in a mili second i guess but repeteadly when i stream a video or open a game. At first i thought it was the speaker but when i connected a bluetooth audio it also gave same output. It happened too with my headphone.
So i guess its not my speaker. What is happening then? Its so annoying me. Please kindly help me, im so desperate. Thankyou
Ps, ive already done hardware diagnostics and nothing found
