There is this blue little blinking light next to my power button on the top of the case. I have only just noticed this now and am quite worried. The PC was built by me on the 23rd June. The light is next to the mic, headset and 2 USB 3.0 ports. It is like a little cup symbol. This happened when i was playing a game.

Could it be my hard drive? I have a 1TB WD Black
My SSD? I have a 120GB HyperX

This is worrying as i have only just noticed it, but not before. Any help is appreciated, thanks.
