PC not responding when i push on power

[sander17]

my new pc got delivered yesterday(components were) so i decided to build it yesterday evening/night and this morning, i did everything correct (GFX card, dvd-rom, motherboard, hard disk, cpu) and connected all of the onboard cables and pc case cables, i connected it with the main powercable, a LED popped up in the case, but it wouldn't start up

now i think it has to do with one of these two things, but i can't find anything where they should fit into:

What was it?

 

[MrMr]

haha. All plausible. I was thinking he plugged the power switch cable on to the wrong pins. :lol: :lol:

Probably the Soft-On power switch incorrectly/not installed, since he did mention that an LED lit up, but the system didn't turn on when he pushed the switch.

well you know the powercable, looks like a square-cube, with 4 pins? you have 2 pieces of them, and i managed to put the wrong one in the EATFX-something port

Important thing is that you figured it out. Good job.
