Hi everyone, I recently finished installing the last components into my self build and like I expected it won't boot (I figured this was normal for a first timer).

I have been looking at other posts and looked through the troubleshooting thread too. I ended up taking all the components out of the case again and set up my motherboard with the processor, ram and gpu. I wired the power switch from the case in and it wouldn't boot properly.

The gpu fans would spin a little and then stop again and nothing came up on screen. A friend suggested maybe I didn't have a big enough psu, so I took out the gpu and tried again and this time it booted, and I got a screen come up.

I tried it again just to make sure it wasn't a fluke, plugged an ssd in this time, and it came up again.

At this point I felt happy I had found the problem and put everything, apart from my gpu, back into my case. I tried to boot it back up and I got the exact same problem as before.

One of the troubleshooting steps says about the motherboard standoffs, could anyone elaborate on that, do I just screw these in and it would maybe work? Is there something in particular I should look for if that was the issue?

And I also would like to know if my psu isn't big enough, I used a few online calculators before I bought one and after I built it to make sure I had a powerful enough one for my components and they all say I do.
I just tried Cooler Master's and it came up with: A recommended size of 385ish

My specs are:
Mobo: Asus H110M-K

CPU: Intel I5 6500 3.2GHz

Ram: Corsair Vengeance LPX
1x8GB 2400MHz

GPU: Gigabyte 1060 6GB

Storage: 1TB WD Blue 64MB cache
120GB Samsung 750 evo

Fans: 2x Corsair ML120 120mm
1x Corsair ML120 Pro 120mm
2x Corsair ML140 140mm

CPU fan: Cooler Master Hyper 212X

Fan Controller: NZXT Semtry Mix 2

I have a DVD R/RW

Psu: Corsair CX 550M 550W


I'd greatly appreciate any help or suggestions :)

Edit: My case is a Corsair carbide 100R

First of all, your PSU i good enough.

1. Check if you have put the card correctly into the PCI-E slot
2. Power cable to GPU connected properly
3. Maybe you need to change primary graphics from your onboard graphics to the dedicated graphics in BIOS.

Thanks for the ideas! I did some tinkering, I took a look at everything,used a torch too, and I could just about see that the top of the ram hadn't locked in properly, I think it must have just sat in to boot up that one time and then when I put it back in the case it came back out. Everything works fine now, just have to tidy up the cables :)
