So recently I've begun using my relatively old PC (2016) if I'm not mistaken, just for drawing art digitally. After using it for a bit, it would suddenly just completely shut off. It would be making as much noise as it usually does before shutting off at random as well. So I thought I'd clean out dust from everything with pressurized air and try to manage the cables a lot more nicely so that it may perform better and just last longer. I also tried my best to ground myself everytime before putting my hands back inside my case as well. However, when I turned it on, it would do only just that. Turn on. Nothing else would happen. No boot up sequence, no RGB light up on keyboard or mouse, monitor would detect a power source but there would be nothing displayed. I pose the question, is my PC just done? I've seen other threads saying that it might be the power supply (EVGA 600 B 600W) and while I'm open to just getting a totally new PSU, I can't test and see if its the problem. I'm now wondering what is should do. Anything helps.
