Looking at the manual for that board, there should be a column of 4 lights towards the top right of the board that illuminate in sequence top to bottom - which ones light up?
2nd red light from the bottom of the 4 lights

The manual suggests that's a problem with the GPU. The order it gives top to bottom is:
What GPU is it - I see you mentioned Sapphire, but didn't spot a model?
Sapphire Rx480 4gb, tbh i thought it was a 580 that i had spare but after closer look on the card its 480

How many power plugs does the GPU take and if it's 2 are they from 2 separate cables from the PSU or have you used a splitter?

Also sometimes the gpu may seem seated but might not be fully in, be worth just making sure the clip at the back of the pcie slot is securing the tab on the gpu and checking it all looks seated ok.
huge thanks everyone for things to try, but i have had no luck and despite the LED lights lighting up all the time on the GPU that say Sapphire it still cant get post screen or anything past No signal and i took a gamble on another MB because theres no way i will be able to afford a New GPU even if i can find one with the way prices are. even a 580 / 570 would be amazing if i could find
tried the bios switch on the gpu, but nothing

Have you plugged in the 4/8 pin to the Mobo?I can't see it in your pics myself
Maybe the LED is getting power through the motherboard slot.
Check both ends of the GPU power cable to make sure it is fully connected, also check for any damaged/misaligned pins.
If the PSU came with a second PCI-E cable try that, if not try the second connector on the cable.
Is the GPU sagging? try propping it up if it is.
