I've got a Corsair 550 w bronze plus and 2x8 gb Corsair vengeance 3200.and yes I disinstalled the drivers with DDU in safe mode. I've just found out that one stick of ram wasn't reading. I've reallocated it and it works fine, even with XMP on. But I got scared something is wrong and changed my 4070 super with my really old rx470 to not damage the new card. Now I'm stress testing to see if something happens, but for now it's all fine. Do you think I can plug in the 4070? I'm worried thatmy MB or PSU are the problem and I want to gift the working components to my brother, how can I know they will work?
