Hey everyone, recently there has been coming some strange noise from my computer. I haven't been able to pinpoint it exactly, but I think it might be coil whine from my PSU. I managed to take a recording of it uploaded it here: http://picosong.com/nH4Y (you will need to raise the volume quite a bit, the sound starts at about 10 seconds in) As you can hear, it's not constantly there. It lasts for 6-7 seconds and then its fine for about 25 seconds. Any help would be greatly appreciated.
