Why is my RX 480 not working at all!

I just bought the RX 480 and when I tried installing it and plugging it into my monitor (ASUS VS247) via hdmi the monitor said there was no signal (there was only a signal when connected to the motherboard or the old GPU), on top of that the fan in the RX 480 does not work properly, it starts for quarter to half a second then stops for a while and this process repeats, the card is receiving power though since it heats up. Does the card not like my motherboard (ga-z77x-d3h)? Did I buy a shitty card off of eBay? Did I mess something up? Please help, and I'd be happy to include more info if needed.

Possibly a faulty card, but what is your power supply make and model (such as "SeaSonic X750", not "750w PSU")
