elementalfx Posted November 11, 2014 Share Posted November 11, 2014 Hello guys can anyone help me. I have got pretty new lenovo y510p dual 755m. Yesterday I played Wolfenstein New Order and sound was working, Nvidia notified me about new driver so I updated but shortly I rolled back as it was giving poor performance but I went to bed turned off computer and now computer is making little knocking sound in left speaker every 2 second periodically and sound is not working. Headphones are ok but speakers looks like dead. I dont know why, its pretty new computer. And also knocking sound starts from very start of computer and I mean by pressing power button when windows boots. Sending to lenovo is not an option for me. Its out of warranty as I repasted it month ago. Quote Link to comment Share on other sites More sharing options...
