I have this pc that I built from scratch and everything is new except for the psu. I was able to use it until today when it suddenly did not power on. I tried reseating everything, swapped power cables, used the screwdriver method to no avail. I also did the paperclip test to my psu and the fan worked. Now I also did the paperclip test with the 24pin connected to the board and it started working ( lights and fans all turned on including the gpu and cpu coolers) but I did not do it for long because Im worried it might damage my other parts. Is this a psu issue?
