My old 5 year gpu recently died and so I decided to get a new gpu (RX 580) without upgrading my other parts. Everything works fine, however sometimes when i'm playing a game my PC will just randomly hard freeze for around 20-40 seconds then goes back to normal. I know this isn't a temperature issue because ive seen it happen under 60c. It's also very random, sometimes it would have two 20-40 second freezes back to back in the course of a few minutes and sometimes once every few hours. This has also never happened with my older gpu, can someone please help?
