Just as the title says, I am getting a weird buzzing noise but as soon as I touch the case with my finger, It stops. I tried to record the noise but my camera did not pick it up. Anyone know what It is? I took my right side panel off but it still is making the noise, it is just quieter.
 
Solution
Tighten all the case screws, plus the ones on your psu and mechanical hard drives. Anything with moving parts really, could be the case fans even.
