Hello. Recently, I bought a G513RM. It works very well and I had no problem with it, but for some reasons, I can hear a strange stuttering sound coming from the upper of the keyboard or in the upper part of the back frame. The sound comes from the computer itself and it goes on constantly. This sound can only be heard in the Windows environment (even the initial stages of installation) or Ubuntu and is not present in the BIOS environment. Actions taken but without effect : 1) Removing or disabling sound drivers (although this sound is far away from the location of the speakers). 2) BIOS update and installation of hotfixes provided by Asus. 3) Checking the fans (the sound can be heard even when the fans are off.). Is this a hardware problem or can it cause other problems in the future?
