I have been using Linux for around a year now and I'm not sure whether this is Hardware or Software problem.
I often am on Skype and playing Games at the same time and when I load a game or anything intensive i can hear a quite high pitch tone coming from inside my PC. I have narrowed the sound down and believe it is the Hard Drive.
This high pitch tone also goes through my microphone as interference and my friends can hear it over skype.
This problem does not occur when I am using windows.
I was wondering if there was any diagnostics i could check and see whether this is hardware or software fault.
I have already tried uninstalling alsamixer and other sound drivers and graphics drivers, which did nothing.
I have also factory reset my Bios to make sure there was no conflict happening there.
I was just wonder if there was anything i could try and run diagnostics or troubleshoot to just avoid the problem
