I got an InWin GRone computer tower
Gigabyte 890fxa-ud5 motherboard
Crucial 8GB DDR3 1600Mhz Ballistix Sport Memory
AMD processor
2TB Seagate hard drive
Graphics card (can't remember which)
Corsair Gaming Series 2013 Edition

I have put all correct wires in etc, when powering the computer, all motherboard lights come on, all fans spin (graphics card, Psu lights&fan, computer fans and processor fan)
But no post is coming from computer.

I have tried plugging in a monitor, nothing shows up.

I have tried removing the ram, putting the ram in different slots, tried just one slot, same problem

I've tried moving the graphics card into a different slot

I have tried unplugging the hard drive.

I have tried powering the computer from motherboard and resetting CMOS, nothing happened

Anyone know what else I could do?

Thanks for your help.

P.S, not sure if this is in the correct section of forums, could a mod move it if incorrect please?
