Re: asrock b85 m pro 4 buzzing noise when gaming

First, it can be difficult to locate sounds or noise generated by PC components, particularly if they are higher in frequency. I'm not saying you are wrong about the location of the noise, but it can be difficult to truly locate the source of the noise.

All sounds are mechanically generated by vibration, although the vibrating part may not be obvious.

Given your board, the upper right area has the memory slots and memory, the voltage regulator components for the memory, and the 24 pin power connector. Nearby but to the left is the eight pin CPU power connector and some of the CPU voltage regulator components.

Simple things you can do is check the mother board screws for tightness, and try removing and connecting the 24 pin power cable again. When the cable is removed, check the metal connectors in the cable itself, to see if any have been pushed up out of position, so are not making a good connection with the pins in the board.

Gaming increases the load and the stress on power generating components. Parts that can vibrate under various loads are usually inductors (the dark grey cubes) and even the capacitors can create sounds. You can't do anything to stop those parts from vibrating besides putting silicone caulk on them, as used in PC power supplies, and even that might not work. The vibrating parts are not faulty or will fail because of the vibration, but the noise is annoying.
