Hi MacSan,
Can you do the following?
If you have already Windows installed in your system, please insert the old card and once you boot into windows, go to device manager and uninstall the graphics driver.
Once you do this, shutdown the system and unplug the power, press the power on button for a few seconds to drain the power.
Install now the new card and see if everything is working. Also good to reset the Samsung SD590 screen.
Regards
