Computer turning on then off repeatedly

Just finished my first build, plugged it in and everything and it turns on then a couple of seconds later it will turn off again and around 4 seconds later it turns back on again, it does this repeatedly. What are the causes of this?

gigabyte z77-d3h
msi 7950
patriotic 8gb ram
seasonic gs 550w
seagate barracude 500gb

Are all cables plugged in? (CPU, motherboard, GPU power etc?)
Did you use standoffs?

All cables are plugged in and what are standoffs?

Motherboard standoffs, you need to install them before screwing the motherboard into the case. If you don't you could end up seriously damaging your motherboard.

they have been screwed in.

As above try with just one stick of memory, then try with no grfx card and maybe a bios reset.

How do you do a bios reset

Doesn't appear to be the ram, I have removed one stick and it still doesn't work

EDIT: removed the graphics card and it still doesn't work
