Very randomly, sometimes once in 5 hours sometimes five times in a minute i hear a very strange sound coming out of case. Its not loud but its very different from the noise my fans or hard disc make. Im suspecting its the psu. I have it for 3months now and it started to make the sound few days ago. Its like a bzz but i can hear it for only maybe a second. Its no doubt electric sound but im not sure if its the psu. I have inspected all caps on motherboard and i didnt see any bad ones. I can sometimes hear it while my computer is off. But the sound stops when i swich pc off via the PSU on/off swich. I tried different power outlet. Pc works fine, no lag, freezing, bsod, error messeges. Its driving me crazy. Should i worry? How can i know that its indeed the psu?
