Some things to try first:
- Reseat the graphics card &/OR make sure that it is seated properly.
- Set the BIOS to load optimized OR fail-safe defaults.
- Check the specifications of the graphics card and compare them with the specifications of your motherboard to make sure that the card is compatible.
Make sure to note what happens after each respective step and reply with results.
