Ok, i have a problem with my new build. Everything is working as it should, but one of my components is making wierd sound (i cant really name which component it is or what it sounds like, but it reminds me of fax machine sound, only quieter). I tried listening, but could not say where does it come from. This noise is not constant, it happens when I boot my computer (during windows startup), and when pc is working something (most of all, when i select text in files, sroll up and down in internet browser etc.) My first guess was that it was my GPU, and I tested my GPU in FurMark. No noise at all, only cooler noise. I ran prime95, no noise, only cooler noise.

What could it be?

My build:
FX-6300
Sapphire's r9 270x dual-x GPU
ASUS m5a97 r2.0
CM 500W B-series PSU
8GB 1600Mhz ddr3 RAM Kingston Fury (working on 1866 Mhz)
500gb wd blue hdd. (i checked my hdd, it's not it for sure).

If you need more info, just say. I would really like to know what is causing this noise.

Thanks.

I played a game for a short time, but I'm still not convinced this is coil whining (noise from that video was constant was changing frequency during gaming), as this noise is occuring only during first few seconds after loading is finished.

Today i listened with plastic tube, and figured out it really is my PSU. What is the best thing to do now? Look for a way to fix it or return it to store?
