Random shut down unable to turn back on PC

StephenSchneider95 · Mar 14, 2016

So here is the background information. I was playing games on my PC and my computer just spontaneously shut down. I tried restarting it to no avail. When I press the power button on the front of my case I hear the power supply click but no system start.

Just want to reiterate I have had no problems up until today when this happened.
I have been told it may be the graphics cards causing issues, which is why its in this subject.

Power supply - corsair HX750
Motherboard - Fatal1ty H97 Killer
Graphics Card - PNY 970
Samsung SSD
Intel I5 Processor.

Probably the power supply. When you click the power button, do the fans kick on for a brief second or does absolutely nothing happen at all?

So when I press the power button I can hear a quick click coming from the power supply. But no fans kick on or anything.

If it a power issue try pulling the gpu and see if the ssytem post using onboard video. if it does try the gpu in another pc to see if it the pc or the power supply. with the power supply if you have a volt meter check the power at the pins. the black wires are ground.

Yeah that'd be the power supply. No other way to put it than it hit the grave.

I will try pulling the GPU out and see if there is any start up, I just started building these computers so I don't have a volt reader.

Pulled the GPU out. Still nothing past the click in the PSU

Well that sucks, figured a Corsair would last longer than this.. thank you though.

Are these all new parts? The HX are great units, but if it's new it could have a fault. And Corsair doesn't make power supplies, they sell them.

All the parts are about a year old, minus the SSD which is like 5 months.

Try the paperclip test on the PSU.

I will definitely try this and update with anything I find out. If you have the time could you maybe link some good PSU. I mostly use Newegg for this stuff.

if your using a stock cpu cooler check that it on right. also check for any lose ram or parts. power supply not turning on may be a dead short or safty part of mb is on. try clearing the mb cmos see if the cpu over heated.

Thank you for this information I will definitely look into it, although I think I may increase to a 900-1000W based on the new hard drive I am putting in. I completed paper clip test, failed it miserably so I am thinking it is the PSU that is dead. Thank you for your help.
