Power On and nothing

I build my pc using tecmo34 step by step guide.

When I power on the system, nothing is working (fans not speeding) I know the PSU switch is on because I can see the orange led from the LAN illuminated.

With rams and video card on, when power on, I see a small red flash on the debug led.

I tried rebooting one ram at the time and and hear the beep, see the flash.

I booted with all rams and video card out and, no flash, no beep.

I tried cmos but nothing.


Did I miss something on buildup? I reread the guide many times, redid it but still the same problem of nothing happening when power is on.

Is my PSU d.o.a?

I'm able to jump start my PSU so I know that's not the problem.

Now I wonder if it's the motherboard that is d.o.a.

If a motherboard is defective then I wouldn't see any led illuminated right, I wouldn't be hearing a small beep sound too right?

Can anyone tell me how to check for sure if it's dead or not, (like I did for the psu by jump starting it).

At least if I know nothing is d.o.a then it means I've done something wrong in the wiring process. I just don't understand why the psu can work alone but if I connect it to the motherboard it doesn't work. I've connected the 24 pins, 8 pins so the fan of the psu should work when connected to my mobo right?

Does it mean something is shorting my mobo and cutting the current?
