Hi,
I have just purchased a HP Pavilion 15-n014sa in the last week and its justed started ri freeze and make a buzzing noise while playing any audio. I thought it was maybe because i updated to windows 8.1 so i did a system restore to before the upgrade and it seemed to fix it but then today i downloaded skype and the same thing has happened so i unistalled skype and did another restore but the problem is still occurring. Id be greatly of any help, Thanks.
