I had a RadeonHD 6770 and switched to a GTX 660. After switching there is no display being brought up now.
Things I've Done -
I've made sure it is slotted in all the way to the PCI slot.
I ensured the 4 pin and all the connectors were connected all the way.
I have tried switching back to the Radeon GPU and still no video.
I put my HDD into another PC and it booted up just fine.
I put both the 6770 and 660 into another PC and they worked aswell.
