A couple of weeks ago, this started happening. The very first startup of each day that I turn on the computer it makes this weird buzzing noise then it goes away after being on for two minutes. If I turn off the computer and start it up again the noise isn't there so it only happens at the very first startup of the day. I took it out today to clean it thinking it was the dust since I haven't cleaned it since I built it earlier this year back in May. But when I started it up, the noise was still there. I looked at all the fans, nothing seems to be between the blades that could be causing the noise and I use a SSD so it wouldn't be that right? What could be the cause of the noise?
