Ok, so I have this computer that I built about late 2016. It's worked perfectly fine for me for the past since I built it up until about a week ago. I turned it on and opened the applications that I usually open, nothing that I haven't used before, Razer Synapse, Discord, Google Chrome, and Steam. Suddenly within less than a minute of turning on my computer randomly shuts off. It doesn't turn back on. I plug it into various outlets around my house and the computer isn't turning on, all that's happening is a little flicker of the LED lights which considering they're plugged into the motherboard means to me that the motherboard isn't short circuited. I believe the PSU is short circuited but I am not sure. I cleaned out all the dust in it and still nothing is turning on other than the slight flicker. I've already tried resetting the breaker in my house and can't think of anything other than getting a new PSU. Any help is much appreciated.
