First-time poster here. I ran into a problem after upgrading my rig with an RX 480 today. Everything was working great but then after a 7-hour straight gaming session with Witcher 3 Blood and Wine (which by the way is AMAZING) I got artifacting and then everything went black and the sound cut out. I reboot my PC several times, but nothing would come up. After looking up the error code on the motherboard, I found that it was "No VGA present" so at first I thought the card was dead and I put back in my 750 ti, but it too would not work with the same error code. So I put the RX 480 in the second PCI-E slot and now everything is working just fine. After everything was A-OK I tried slot 1 again and it failed again, so now I'm in slot 2.
I did a Google search to see about this problem and I found several articles about the RX 480 overdrawing power on the PCI-E slot. HOWEVER, I'm not sure I'm ready to pin this issue on that yet, hence why I'm posting. I feel like having the card for just a day and only having a 7-hour gaming session is too soon to cause failure. What do you guys think? Maybe it's just a coincidence? I'm no expert on power draw or what overdrawing would actually do to a slot or even the motherboard as a whole. I also feel like if it was due to overdrawing of power that the whole south-bridge would get messed up and then the second PCI-E slot wouldn't work either, but it does work. I could be wrong in thinking that, though. Anyway, thoughts?
