Issue Details
- replacing NVIDIA GT610 with Radeon 6670.  Installed card, screen came up fine, realized NVIDIA drivers still on system, uninstalled old NVIDIA drivers, rebooted and screen went black, with intermittent blinking.  Had to reinstall NVIDIA card to get display back.  Do I have a bad card or is there a driver issue?

Use Driver Fusion or Driver Sweeper in safe mode and get rid of all NVIDIA and AMD related drivers, then boot normally and install latest drivers from AMD support page.
