No signal please help!

[Pcbuilderbrah]

So ive recently built a pc and everything has gone perfect until i turn it on and notice that the monitor says that theirs no signal. I dont know if its the wiring because all the fans turn off, even including my gpu. Also could it be my monitor?

My setup is

X4 760k

Gigabyte f2a88xm hd3

Powercolor radeon r9 280

Seagate 1tb hdd

Corsair 750w

8gm crucial ballistic ram

Make sure your RAM is seated well, also you mentioned your fans. Do they turn on, then quickly turn off? Or do they not turn on at all?

Also make sure that the PSU switch is set to on, I don't know how many embarrassing moments I've had with that one.

The cpu fan does run

The gpu fan should not be off, sounds like a power supply or motherboard issue. Does the cpu fan run?

It does run

I don have an optical and i assume yes the hdd works, since it make sound when turned on

I'm not sure then, my guess would be motherboard or psu.

Because i just bought a new psu and i jst got the motherboard yesterday. I was very delicate een wore a esd strap.
