Bought this card with a recent holiday bonus earlier this month XFX RX 480 8Gb model. I installed it, replacing my Radeon 7950. I boot it up, and about 30 minutes later, my screen turns off. I try it again, about 10 minutes later, again the screen looses signal. Over the next few days i keep trying it, but the card stops sending a signal to my display (ACER 1080p using DVI port.) I connect my older 7950 back in and it is working just fine. Uninstalled and reinstalled the drivers with AMD uninstall utility the first time, and DDU the second time, same issue. RMA'ed the unit, and still having the issues with a second one. Judging by the amount of responses I'm seeing online there seems to be a trend. What am I doing wrong here?
