Ok so I got the new R9 280x gpu. I came home from work and installed it only to stare at a black screen...I uninstalled my other gpu driver b4 I installed it made sure it was completely slotted along with the new ram. The card boots up and the fans run wether I have the 8pin and 6pin plugged at the sAme time or by there selfs. The box says it needs a 500w power supply and I have a 650w antec. When I put the old gpu back in it boots up fine with the screen. The only thing I haven't tried is going into the bios and making sure the pcie slot is set as the default. I've never had this issue and how do I tell if the card is DOA when the fans come on? Or is it just not compatible with my MOBO?
