That's when the PSU senses something is wrong and shuts down rather than blow something up. Or a bad PSU.
This is easy to diagnose as I unplug everything I can to see if it will power up. If it powers up I can add a few items at a time to see which part it was.
If it didn't power up with everything removed I move the PSU and the motherboard to a cardboard sheet. If that doesn't power up then I'm looking at the remaining bad parts.
But I'm not done yet. I can test most PSUs with THE GREEN WIRE PSU TEST (google it) and a Volt Meter.
Hey everyone I have an issue that has me stumped . So basicly what happend was I was playing my game and it randomly locked up but dident shut down so I manually powerd it down and when I went to power it back up it did nothing but make a constant buzzing noise but I couldent tell where it was comming from so I took off the side to take a look and when I hit the power button all of the fans/leds will turn on and fans will make about 1 or 2 rotations untill it all shuts off again. There is a constant led that tells me that the mb is getting constant power. And now this morning it dosent make the buzzing noise anymore. ive went thru cleaned my whole case re seated my ram checked all the cables and nothing looks wrong thats why im here I ran outa ideas
