Radeon RX580 dead after cpu upgrade

[Snowy792]

Now bear with me as I'm quite new to the whole pc building scene.
I've been using a prebuilt system for about a year and decided to upgrade from my old i3-2120 to an i5-2400 and my gpu from my GeForce GT 730 to the Radeon RX580. I got the graphics card in the mail first and decided for the first few days to try it out with my i3-2120 and it worked really nicely. However I've just installed my new i5-2400 into the system and tried to boot it uo only to get motherboard beep codes telling me the gpu was dead. I've tried a few trouble shooting methods to no avail including putting the gpu into a new system to test (same motherboard beep code response) and resetting my computer entirely. I want to know if theres anything else I could possibly try before I have to send it back and buy a new card entirely.

+note the cpu isn't at fault as my GT 730 seems to run perfectly fine with it installed aswell.

 

Specs :

Gateway DT71 Motherboard

Intel i5-2400

GeForce GT 730

Aero Cool Intergrator MX600W PSU

2x 2GB DDR3 Ram

i think you're gonna need to send it back. if cpu aint the problem. and you tried it in a different system. then theres nothing else left. send it back and get it fixed

Have you plugged in the power cable for the graphics card?

[Snowy792]

Yeah. I've plugged in the card and it turns on with both leds working and fans rotating but if the pc gets past POST no display is shown and after about 5 minutes it reboots and enters the endless power cycle again.
