Explanation
The PC successfully completes POST (Power-On Self-Test), which means the BIOS recognizes and initializes the new video card correctly. The screen going black specifically when the OS begins to load indicates a driver conflict - the OS is attempting to load the existing video driver, which is incompatible with the new card, causing a display failure. Booting into Safe Mode loads only a generic VGA driver, bypassing the conflicting video driver, which should allow the OS to boot and let the technician install the correct drivers. Reseating the card is unnecessary since POST succeeded. Flashing the BIOS is an extreme step not warranted here. Replacing the card again is premature before simpler steps are tried.
