I have recently installed my new MSI R9 280x and also reinstalled windows down to me being tired of windows 8 but in doing so now my motherboard (ASUS P8H61-MLE) doesn't recognise the old card or the new card. I have tried Flashing the BIOS and un-installing the on board graphics but it still doesn't pick up the new card and therefore doesn't let me install the drivers i just get Install package failed everytime. There is ample PSU (750 to be exact) and the card powers up fine i just seem to get a blank screen if I connect through its VGA. Through installing the the new card and removing the old is it possible the PCI-E slot is damaged or am i missing a driver? i have spent all night trying to solve this Please help!
