Recently i started working on a project that has to do with an old pc from 2004, the problem is that the PSU started to make high pitch sounds and i wanted to know why it was happining amd how to fix it? Also i don't have any GPU connected to it all i have connected is the motherboard and Pentium 4 CPU AKA a Pentium Turd...
