So my PC randomly shut off after a window update during shut off. I tried turning it on but it didn't work. I tried leaving it be for a whole day and plug it back it, doesn't work. I looked it up and tried the paperclip in the 24 pin cable to check if the fan works and when I start it, the fan spins for a few seconds. So what seems to be the problem?? Is my PSU dead or not? The fan works I think, so why isn't everything else?! Please help I'm a poor guy and only had this computer for 10 months..
