So, I got an RX 580 on eBay and the listing stated "mint condition, less than 6 months old". When i got it, it was working perfectly fine. 2 days later, it is now giving me crazy artifacting after a few minutes of being on the computer, but I only get this kind of grace period with the drivers Windows automatically installed for me. Which appears to be Crimson 17.1.1. When it starts to artifact, it will only stay on for about 30 seconds then the computer will reset. I also noticed a different kind of artifacting, kind of like an overlay or something across my screen. My second monitor turned off and in the device manager it gave a code 43 that the drivers had stopped working. I'd like to know what's actually wrong with it since I just got it.
