Hello everyone, so i have this rig i've been using for several years until recently I started to hear some kind of "short circuit" sounds while turning on the PC ,sometimes it doesnt even start so i have to re-plug over & over in hope it starts, even after that i get random shutdowns However i tried: -Cleaning the PC -Using different cables So any ideas how to fix this ? cause nobody want to get stuck in quarantine without his rig and thaanks P.S: For now I can't get any other PSU
