My motherboard powers up, but my rig won't boot!

nathanthe1rst · Jun 15, 2013

Hello everyone! I'm new here. I signed up because i have a somewhat troubling issue. I built my computed during the whole night, following multiple video tutorial instructions. the next morning, when i woke up, I tried to turn it on for the first time, but nothing. I realised that i didn't turn on my monitor!
So i turned it on. And still the same reaction... When I turn on the PSU (seasonic 620w), my motherboard's (gigabyte z77x-ud3h) little power logo lights up, but when I hit the power button of my case (fractal design r4) nothing displays on my monitor! Please help!

Please list all the components in your build. Then please proceed to answering the following two preliminary check questions:

1. Is the 24-pin motherboard power connector plugged in properly?
2. Is the 8-pin CPU power connector plugged in properly?

i am positive that both are plugged in correctly

ur6beersaway · Jun 15, 2013

Did you load the mobo disk? Do any fans spin? plug in a speaker any beeps?

ksham · Jun 15, 2013

Did you plug the monitor to the GPU or motherboard?

nathanthe1rst · Jun 15, 2013

the mobo disk?
absolutely NO fans spin.

nathanthe1rst · Jun 15, 2013

Check PSU= http://www.youtube.com/watch?v=tqPTD6LXQsg

what if... my psu was defective! it's what this technique is telling me ...

Remove the GPU and try again. It's really recommended to test with a very minimal configuration -- power supply, motherboard, CPU, and one DIMM of RAM. Nothing else should be hooked up. Double check to make sure. If you are not sure, then detach all components and start building it back up from scratch up to those four components. Then stop and test.

nathanthe1rst :

The monitor needs to be plugged into the GPU.

or try without the GPU like the other poster said.

ur6beersaway · Jun 15, 2013

Did it pass, Green & any black? if not it's DOA unit. Check into RMA the psu.

nathanthe1rst · Jun 15, 2013

ur6beersaway :

i don't understand?

smeezekitty · Jun 15, 2013

nathanthe1rst :

Please try either without the GPU or with the monitor plugged into the GPU.

nathanthe1rst · Jun 15, 2013

i didn't try with the monitor plugged into the gpu, i'll update you in just a sec

nathanthe1rst · Jun 15, 2013

monitor only came with one "mobo-to-monitor" cable. do i plug that one into the gpu?

smeezekitty · Jun 15, 2013

What kind of input does the monitor have? VGA, DVI, HDMI etc?

nathanthe1rst · Jun 15, 2013

vga, hdmi and dvi
credits to you all for being patient with such a noob

smeezekitty · Jun 15, 2013

Any of those will work fine. But VGA may need a DVI<->VGA adapter.

nathanthe1rst · Jun 15, 2013

yeah, all i got with my monitor is a vga cable, the monitor, user's guide, and power cable...

smeezekitty · Jun 15, 2013

Did your GPU come with a VGA to DVI converter?
