PC only booted once?

[BeakTrots]

Put everything in, plugged it in to an outlet and jumped it with a screwdriver because my case power button is broken. It's my first time building so I'm pretty scared. It boots! Fans start spinning and I can hear it working. So i go to unplug it and I take the cord out of the psu. I try to boot it again and I have changed nothing, and it just wont boot. No fans, no sounds. What could have happened that made it not boot a second time?

Is the switch on the PSU switched to the "i" position? 

[Oskar94a]

Did you put the cord back in?

Yes

My psu doesn't have options to change?

Wait a couple of minutes...

Have you tried turning it on and off again?

I've waited 30 minutes since last boot

Have you tried turning it on and off again?

I can't turn it on is the thing...

that sounds like nonsense, there should be a switch on the back of the psu like a light switch

Do you have a GPU plugged in? If so, that PSU might not even be powerful enough to run your machine.

I'd unplug everything, plug a fan directly into the PSU, take a paperclip and bend it into a U shape. Stick one end into the green wire and the other into a black wire (any one will do) on your 24 pin connector. Then plug it in. If the fans start spinning than we know it's not your PSU. Might have shorted something out on the motherboard.

does your psu make a popping noise when you plug the cord in?

Yes it does, does this mean it is working?

[BeakTrots]

I wont be too disappointed if it is the motherboard or power supply, as I have a warranty on both and they were both only around $30

bump

put the red switch back where it was when you got the PSU, That changes voltage , if you did it while running you've fucked the PSU( there would be smoke and a bang)

*Speaking from experiance

[VettleBolt]

bump

Then try boot again

UPDATE I FIXED IT! it had to do with me starting it with a screwdriver, unplugging it, replugging it and trying to start it again
