System won't POST

[Doughmay]

Hi! So I recently assembled a build and I plugged everything in. Then when I go to turn it on, the fans spin, then stop, no POST. Nothing. So, I have no idea whats going on, I've checked the PSU, and the CPU, and RAM, they all are OK  I also replaced the motherboard. So do you have any idea whats going on? Halp?

Do you have a video card installed?

Yes. I have a powercolor RX460 powered through PCIE.

You sure everything's plugged in right? All the power cables?

I think so, I've checked the mobo guide and it seems OK.

Take it out and see if the system responds the same way.

Powered through PCIE? Do you mean PCIE slot or PCIE PSU cable?

 

I'd hope the latter.

Technically, cards are powered through both. PCIe slots provide up to 75W of power for video cards.

Same response of the system.

How many sticks of RAM do you have?

Well yeah, so I suppose any system would post regardless.

No, the 460 draws power straight from the MoBo, doesn't need a PSU cable (I think it's cause of the 75 W max limit through the slot). That's fine.

Oh. wow. News to me.

@Doughmay, do you have an LED screen telling you a two-digit number, or a motherboard speaker at hand?

@Doughmay, do you have an LED screen telling you a two-digit number, or a motherboard speaker at hand?

No, only a LED to display power.

1 DIMM I've tried another with the same result

This might be a stretch, but try resetting the CMOS. Is the motherboard touching the case at all directly?

Is that literally the only LED on your motherboard? Sometimes they have LEDs that are either on/off to display the status of different components. Check your manual to see if it references anything of the sort.

You may also want to check your manual and ensure that 1 DIMM is in the first slot of a (or one of the) dual channel pairs. To my knowledge, throwing a DIMM in slot 3 aint gonna do you any favors.

 

How many slots does your motherboard have?

Nah, the CMOS resets to defaults, if the MoBo's new (and he also changed it out for another one) CMOS won't do anything. 

I know it resets to defaults, but I'm not ruling it out just because it's "brand new." That's not necessarily proper testing. It may not be likely, but I can't just ignore it because of that.

4 slots, and looking through the guide it only identifies one LED

The mobo is mounted to the case and I think touching the back panel.

If it's touching the back panel(and if my understanding is correct), the motherboard is shorting out.

So, I have to remove the back panel and see if I can get a better response?

Still isn't POST.

You should probably put.. them on the stand-offs?

Back panel to me is the panel the motherboard is mounted to. But that doesn't seem like that's the case. 

 

EDIT: Are you using standoffs?

My case didn't come woth standoffs, so I just mounted it.

You need standoffs. Your motherboard is shorting.

ok, so would i put the standoffs in before the mobo ormobo then standoffs? Would they go into the screw holes?
