Mobo problem? NEW custom pc

I'll be straightforward as *.
I'm tired of waiting and I'd like a solution. I'm sorry if I sound pissed, but I actually am. I've been waiting so long, I've had my components sit there for a while cause of university, now I'm all ready to assemble everything, I follow every SINGLE instruction, and the PC doesn't boot up properly.

Everything spins, everything looks healthy BUT there's no BIOS startup, and my monitor receives NO input at all, regardless of the plug used: mobo integrated VGA, mobo integrated DVI, dvi of my GPU or hdmi of my GPU all seem not to be outputting anything.

I just assembled this pc:
Asrock H97 anniversary
Intel core i5 4690
8gb crucial ballistix sport
1tb HDD WD
Samsung 850 evo 250gb
Gtx 970 MSI
EVGA 650 watt gold GS edition
Corsair carbide 100r case

So, I've CORRECTLY installed my CPU
I've CORRECTLY put the stock cooler on
I've put 2 sticks of ram in the blue slots
I've mounted the mobo ON the suspenders or whatever you call them (now there might be an issue there, I'm not sure. Firstly, the central "suspender" is different, and has a kind of clean, smooth "screw" coming out of it, so that you can't put a screw IN it, but it fits in the central hole of the mobo. Secondly, the screws that come with the case are too short, and the mobo doesn't stay FIRMLY attached to the suspenders).

I've correctly installed my GPU, and I've connected all the necessary cables from the PSU.

What could I do? Any help would be appreciated


 
Solution

Try this first. Remove the standoffs from the case if you can and attach them to the motherboard with the screws. The set it on a table with the standoffs on the table and see if anything from the mobo is hitting the table. If so you need longer standoffs.

If it's just a matter of the crews being too long go the hardware store or computer shop and get shorter screws. Take the screws and standoffs you have with you to be sure you get the proper length.

In the end the standoffs need to be tight in the...
I suspect the problem is with what you are calling the "suspenders". They're actually known as "standoffs" because they make the mobo stand off (away) from the metal case below it so the pins and traces on the bottom of the mobo don't create an electrical short.

You mentioned that the screws are too short and that should not be a problem. I suspect whatever is causing the screws to be too short is actually the problem. That case will fit three sizes of mobos so the standoffs may not all be needed so there may be a standoff attached to the case where there is not actually a hole in the mobo for an attachment a screw. Make sure you have all of the standoffs you need to fit that mobo installed and no others.

The mobo should sit flat on its standoffs. The mobo holes that have little exposed metal "pips" around them are actually grounding electrical connections. When the mobo is not attached to the case the screws should be long enough to go through the holes in the mobo and extended at least 3 or 4 threads through hole on the bottom. If they don't they are not long enough and will need to be replaced with longer screws. If they are long enough to go through the mobo the right amount the problem lies in something holding the mobo away from the standoffs so that it doesn't sit flat on them.

The one with no threads might be an alignment pin rather than an attachment point. You might have to remove it if it is holding the mobo away from the other standoffs. It could also just be a manufacturing error. If there are metal "pips " around the whole it goes through replace it with a normal standoff and screw because those metal pips around the hole provide and electrical ground for part of the mobo.

Once you get the mobo properly mounted then start your build with the minimum components to boot - PSU, CPU, and one stick of RAM. Remove everything else.

If that doesn't boot try your other stick of RAM. When it boots to the BIOS shut down and add your other stick of RAM. If that doesn't boot you have a bad stick of RAM.

The add components one at a time, powering down between each step, leaving the GPU until last. Make sure the SSD data cable is connected to the lowest numbered SATA port and the HDD is connected to a higher numbered SATA port.

Once it boots to the BIOS with everything installed you can then install your OS and you should be off to the races.

Thanks Thx1138v2 for your quick reply.
I'll try the barebones method.
Yeah STANDOFFS, that's what they're called!
But the screws ARE actually long enough, it's just that the standoffs are too short to fully "accept" the screws.
 

Try this first. Remove the standoffs from the case if you can and attach them to the motherboard with the screws. The set it on a table with the standoffs on the table and see if anything from the mobo is hitting the table. If so you need longer standoffs.

If it's just a matter of the crews being too long go the hardware store or computer shop and get shorter screws. Take the screws and standoffs you have with you to be sure you get the proper length.

In the end the standoffs need to be tight in the holes in the case and the screws need to be tight against the mobo to make the electrical grounding connections.

Yup, that did it. Thanks a lot man, you saved me.
My PC runs perfectly now, it's bloody fast and I LOVE IT.

I just removed my mobo, checked the screws (whether they fitted the standoffs or not) and then proceeded to screw the *good* screws into the *good* standoffs (some screws and standoffs were poorly made: thank god there were enough that worked).

So the mobo was tightly screwed onto the case. I then removed one stick of ram (as you suggested), and removed everything else except for the CPU, the CPU fan, one stick of ram and the basic power connectors. I booted the PC and it worked!
So I progressively plugged in everything, I installed my OS, my new drivers and everything else.

My PC now works like a charm and I'm SO happy now.

Thanks again for your help!
