I recently purchased a powercolor R9 380 from Morecomputers, I set it in to my system and there is no video post, and the fans spin alternately.

Without the card in, the system starts up, there is a post and it goes into the BIOS, with all Temperatures at a normal rate(30~40 C).

I've taken photos of my cables to make sure they are plugged in correct.

And here is a Video of what happens to the card once I boot up the pc.

I`m going to take it you were using the on board video solution of the motherboard before you bought and fitted the R9 380 card.

Looking at your picture it looks like you have connected the eight pin 12v E-atx power block from the psu to the motherboard
Just behind the main I/O shield of the motherboard.

And that you also connected the required 12v Pci-e power connectors direct to the R9 380 card from the Psu.

If you have.

When you connect the monitor cable to your on board video output port of the motherboard.
Go in into your bios, find the section that deals with what graphics card and interface to initialize first, the primary graphics display setting.

Change the mode, or option to Pci-e or Peg as the selection.

When you connect the monitor cable to your on board video output port of the motherboard.
Go in into your bios, find the section that deals with what graphics card and interface to initialize first, the primary graphics display setting.

Change the mode, or option to Pci-e or Peg as the selection.
Save the changed settings in the bios before you exit it.

Now fit your R9 380 card back in the Pci-e graphics card slot on the motherboard.
Connect the required 12v Pci-e power connectors to the facing edge of the R9 380 card direct from the PSU.

Connect your monitor lead to the graphics output ports of the R9 380 card.
Turn the system on via it`s power switch on the case.
Everything should now work ok. with a display image on your monitor from the R9 380 card Theashar.

IF not !

Double check that all of the eight pins for the 12v Eatx power block on the board are all seated and connected from the Psu of your
system.

One more thing to check, if you look at the top edge of the graphics card you will see a small switch you can slide left or right.
On some cards it is for comparability to run with a legacy bios of a motherboard, older type boards.
And the other state can be for a motherboard that has UEFI bios capability.
Try switching it over from one position to the other.
