So I built my current PC about 2 years ago. I've had a very good experience with it. I decided to upgrade from an R9 270, to an RX 480. Personally, no compatibility issues stand out to me, except maybe the power supply. Here's my build. AMD 8350, Asus M5A97 Le, 16gb DDR3 1600, 1TB WD Blue, Rosewill ARC 550w, Windows 10. Here's what I did: Unplug everything, take side panel off, remove old gpu, installed RX 480, ran the power connector to it (it takes 8 pin, I used a 6+2) and turned the system on. It seemed fine, but the displays started to flicker. When I finally got to my desktop, I could tell that my PC was just unresponsive. I installed the new drivers via the disc that came with it, and still no sign of improvement. My CPU, HDD, and RAM were all at normal usage. Eventually, after fighting through the slow, unresponsive system, and random screen flickers, I got the blue screen with a display error code (I dont remember). A few things worth noting. the RX 480 I bought was open box, when I installed my old GPU, my system was fine. Please, I'm only an avid PC dooood so any help would be great. ALSO, before telling me to fresh install windows, I only have one hdd and would rather not go through that hassle, but hey, I'm up for anything. Thanks!

Hi Charlie.

There is one golden rule here, and that is even if you buy a new graphics card from the same company that makes the GPU fitted to the card, and has more memory fitted to the card Vs something like the old R9 270 card you were using.

You remove the old video driver from the system while the old card is still fitted to it.

You never pull the card and leave the old driver installed in windows, and then install the new video driver with the new card.

It causes a conflict, and the new card to perform really badly.

So start again.

Download DDU Install it on your system, then run it.
Select remove all ATI drivers and windows registry entries.
Let DDU run and then reset the system.

Run DDU again, only this time select remove all Nvidia video drivers and windows registry entries just to be on the safe side.

Let DDU run then restart the system.

Here is a link to get DDU bellow, download it, install, and run it.

Don`t use the driver supplied with the card on the dvd disk, instead click on the link bellow to get the most recent driver that is compatible with your RX 480 card, and the windows version you have on your system plus the correct bit version of the os 32 bit or X64 bit.

Crimson relive 17.2.1 is the driver version you should download and install on your system.

This will fix the problem once the new driver has been installed and you restart windows OS and let it load back in on your system ok.

I followed your instructions. I didn't run the DDU in safe mode though. Surely that won't change anything. When I booted the PC up with the 480 in it, the resolution was low, but it seemed to work just fine. I followed the link but when I tried to download the drivers, my PC blue screened. I repeated the process and it says there installed, but then it locks up again, and again. Here's the code, "VIDEO_TDR_FAILURE" "What failed: atikmpag.sys" Any ideas?
