So i'm fairly new to pc gaming and I bought the radeon rx 570 8 gb to start out with. As I've had it it's shown to occasionally freeze for a moment, and then my screen will turn black and my keyboard is unresponsive. It doesn't shut down the entire computer as my fans and led's still run. It's so inconsistent that I can play GTA V for three hours straight at max settings with no crashes but it will almost always crash while watching a YouTube video. It certainly isn't overheating since I monitor the temps at all times. I've even tried multiple power supply units with the same results. Does anyone have any advice for this? Maybe there is some settings i can change in wattman?
