6700xt Black Screen Issue

[WaitYouDead]

Before I got my 6700xt I was rocking with intel hd graphics with no problems. As soon I got my 6700xt I have started experiencing problems where when I am early in a game session the screen will go black and I have to manually restart my computer by flipping the power off and on again. After that my pc wouldn’t black screen for the rest of the play session but when I get on to play the next day the same thing always happens and I am very confused on why? Also I do mine on my card when I am not playing so recoup some of the cost as I don't want to sell my kidney to pay my debt. I have tried reinstalling windows, reinstalling drivers, setting pcei from auto to gen 3, getting a new power supply, updating motherboard bios and reinstalling the card but nothing really solves my problems. Can anyone help me? Thanks!
