Monitor wont detect RX 480 anymore

Billzegun1 · Aug 11, 2016

So ive had my rx 480 for about 2 weeks now, working fine on HDMI (havnt tested Displayport as i dont have a cord) but today it just stopped detecting it. The monitor works if i unplug the power from the graphics card and use the onboard graphics, but if i have power going to it theres no monitor whatsoever. any ideas? And yes, its seated properly, and yes, the fans spinning and such.

From my experience, the problem is the PSU.
What is your PSU ?

Have you gone into BIOS and checked to make sure the on-board graphics is turned off and the 1st graphics device is set to PEG (PCI-E Graphics)?

In my experience the GPU has died or there's a physical problem with the power connections or the card insertion/seating.

Easiest way to test is to transplant the GPU into another working computer. This is especially my thoughts due to the system using the integrated graphics. This suggests the PSU is operating (there is still a possibility it's not working properly) but heavily suggests an issue with the GPU.

So, I suggest you transplant the GPU into another computer as an easy way to isolate the problem. If that's not feasible, then try moving the GPU to a different slot (if you can) and ensure that the card is fully seated in the slot (not sideways or partially in) and that all necessary power is attached to it.
