New build turns on then off

My new build runs then turns off after a minute. I dont know what the problem is. I think it might be the psu but i dont know how to check if something is dead or not. Please help. My cpu temp is 35 degree celcius. Thanks.

Does your motherboard have a readout screen or a light indicator of any kind that can give you a readout of any errors?

You'll have to give some context to this problem for better help.

well what basically happens it everything boots and i can acess the bios. Then after a minute everything shuts off.After that i try to turn it back on but it doesnt work. I have to reset the psu to start it again.

Are you overclocking? What are your RAM clocks? What PSU are you running? 

Reset CMOS? Sounds like a bad OC to me.

I found the issue the psu was faulty thanks. Also its a brand new build so no overclocks yet.

thats great, let us know if you replace the psu if it works correct then, so we can put the topic as solved.
