Edit: Problem Solved
Problem solved, after much tinkering, it turns out I had to enter the bios and set the PCIe Display setting to (Gen3) GPUs. It was originally on (Auto) and the other options were (Gen1) (Gen2) (Gen3) . Apparently (Auto) couldn't tell it was a Gen 3 GPU. Very interesting as all modern GPUs and Motherboards should be able to sort this out. Hopefully this helps someone else. Thanks to everyone who helped me :) I appreciate the help no less. Cheers!

Hello there!
I recently just built my first computer and I had no problems throughout. When I was finished, I hooked it up to a monitor and powered it on. All the LEDs and fans (Including the CPU fan and the ones on the GPU) powered on but the monitor displayed nothing. Additionally I know the monitor was connected properly because if it's not connected to anything it will display "Missing signal" on the screen. Once plugged in properly this disappears. Thus I knew it was a problem within my hardware somewhere.
I must admit that i'm definitely a newbie when it comes to this stuff so I had no idea where the problem was. I surfed the web and the forums a bit and they all led me to the same checklist. I went through everything on there with no luck. This included checking all connections, trying with only 1 stick of RAM, etc. And so here I am!

My specs are:
Intel i5 4460 CPU
Gigabyte Radeon R9 280x Windfore GPU
G.Skill Ripjawx 2x4gb DDR3-1600 RAM
Gigabyte B85M-HD3 rev 3.0 Motherboard
Patriot blaze 240 GB SSD
EVGA SuperNOVA 750w 80PLUS B2 Bronze Certified PSU

EDIT: No longer relevant
One key point I will mention is that I am very unsure as to how the wiring from my PSU works I currently have 2 vga cables tucked away, unused because I am unaware if I need them and where to use them. My graphics card came with one 4pin to 2 molex cable and one 6pin to 2 molex cable. The 4pin and 6pin ends were plugged into the GPU since there were corresponding holes. I plugged the PSU cable labeled "PERIF" into the molex end since they were the only molex cables I had. I assume I did at least something right since the GPU fans are running.

EDIT: No longer relevant Lastly, since my power supply is modular, I had to throw in a few extra cables. All of them plugged one end into the PSU but then split into 3 separate ends. I am not using all 3 ends because I only need one or two. Will it still function with only using a fraction of them?


Thanks a ton to whoever read through this whole thing <3. I know it's very long but I tried to be thorough to get a good answer. Thank you again and I hope someone has results :)

It would be nice if you could provide a few pictures within your case and the back of your computer as well! :)

should use the PCIE 6+2 cables to power your GPU, the molex adapters are far from ideal and are often trouble causing.

The description of a cable that splits off sounds like the SATA power cable, is it linked to your drives? Its perfectly happy if the connectors arent fully populated, it makes no difference.

You dont have to have cables plugged in if you arent using them, that defeats the point of having a semi mod / modular supply

I have no PCIE cables on my PSU (Unless VGA is PCIE? I'm sorry I'm very new to this)
And yes I have one SATA power cable and only one is connected to the SSD. Thanks for confirming that isn't the problem

the cables stamped vga... are they 6 pin to 6pin? 8 pin to 6 pin? 8 pin to 6+2 pin?

I have the g series of that PSU, on mine the port on the PSU is stamped VGA but the cables labeled as PCIE, I would assume therefore they would be the correct cables, especially as pcie is most commonly used for video cards/gpu or VGA cards (alternative names for the same thing)

It is connected to the main bundle, not an extra modular connected one, so I can't see what it's labeled on the PSU. At the end it is labeled VGA and it is a 6+2 (Check photos for further reference)

aye, take out the molex adapters and use the vga cables.

6+2 if you have a card version wih 8 pin sockets (couldnt quite make it out) and just leave the 2 loose if they are 6 pin... or one of each like mine :p

then see what happens

Still nothing :(
Good call regardless, I will keep the VGA cables in, maybe it's half the solution
Thanks a ton anyways, really appreciate it.

The following shows up in pixelated grey text "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key"
