Nvidia NVS 510 graphics card was replaced by someone else, because it was thought to be bad. Seated new card, still having the same trouble.
Only two monitors come up at a time, but the 3rd monitor will come on if it's one of the two plugged in.
-Downloading latest driver
-Using different slot on card
-Changing settings in Nvidia control panel
Can't, because 3rd monitor is not detected
