To start off I have recently got a r9 290 and when I had first set it up and installed the drivers everything seemed to be working perfectly until when loading up a game I black screened. I uninnstalled my AMD driver and when attempting to reinstall the drivers I black screened throughout the process. I had a gtx 650 ti before, and yes I made sure to uninstall the NVIDIA drivers. Is it possible the card is not getting enough from my PSU? I am using a 6 and 8 pin that are together, and I received a seperate 6 pin and a seperate 8 pin with the card, but I did not have the correct PCIe caple to be able to plug them in to my psu, so i'm using the same cable I used to run my gtx 650 ti if that makes any sense. I have tried to fix this in my spare time for about 2 days now but any online help guide I haved followed just doesnt seem to work.
