Hello, my PC started making very strange noises at random. At first I thought it could be damaged GPU, I ran a GPU stress test and noise started immediately and it stopped when I ended the test. Today I tried another GPU and problem still persists. I also tried removing RAMs which did not help.

This noise happens only when PC is standing, when I lay it on the side, it is not happening.

Can it be PSU problem?
