Not sure if my motherboard is dead or psu or if I have another problem.

I have just built a new PC and while it was installing windows I left the room. I came back after 5 minutes to see that my computer was off and I could not turn it back on. I noticed that none of the motherboard LEDs were on. I think its probably the motherboard or the psu but I'm not sure.

My components are:
Asus Z97-PRO WI-FI AC
Intel i5 4690k
GSkill 8gb
Samsung evo 840 500gb
Seasonic m12ii 850w
Gigabyte gtx980

Checking your PSU is relatively simple - you can follow the steps in the link below to do a paperclip test or you can google it. The pinout at the mobo end is standardized. If the PSU spools up, you'll know it's something downstream of it - let us know and we can go from there.

I should mention that the test above only verifies that the PSU powers up and puts out SOMETHING. Verifying voltage outputs will require checking with a multimeter.

thanks for the fast reply, turns out the problem is the power supply. it failed the paper clip test. I tested the fuse in the plug and it was fine so now any ideas?

Where did you buy it from? If from Amazon or Newegg, I'd give them a call and request a replacement or return. If you can't return it to the retailer, contact Seasonic and request an RMA. I believe they allow advance RMA, meaning they'll send you a replacement before they receive the dead unit from you, but you'll have to ask.

Kind of sucks to have a brand-new component fail, but at least you know it's still under warranty.
