  1. Do the graphics card fans spin? What model are your MB and PSU?
  2. The first rule of upgrading is to stop and back up to the original configuration if the upgrade does not work.

    Remove the new card and replace the old card or reconnect to motherboard graphics.Does the system complete the POST and boot to the OS?

    Does the new card work in another system?
  3. What was old GFX card ?

    Dis you uninstall old drivers ?

    Did you install new drivers ?

    Is Monitor OSD set to correct input ?

    Does your MoBo have On bard GFX ? Is it turned off ? Did you move GFX cable from on board connector to new card connector ?
