1. Check the manufacturer’s website for the latest available driver updates and install them.
2. Reseat the graphics card in its slot on the motherboard to ensure it is properly connected.
3. Check your system’s BIOS and ensure that your graphics card is set as the primary display device.
4. Check if the power cable is properly connected to the graphics card and the power supply unit.
5. Ensure that the graphics card is not overheating. Use a temperature monitoring utility to check temperature readings of your GPU. If the temperature rises above 80-90° C then you may need to replace the cooling fan or repaste the thermal paste.
6. Check all cables associated with the graphics card and make sure they are properly connected, both at the card itself and at the connection point.
7. Check the video cables connecting your monitor to the graphics card and make sure they are compatible and securely connected.
8. Make sure that the correct version of DirectX is installed, as this can cause problems with graphics performance.
9. Try removing the graphics card and running your monitor off integrated graphics to see if it works properly.
10. Check if the issue persists when using a different monitor or display port.
11. Power cycle your computer by powering down the system and removing the power cord from the back of the case for several minutes.
12. Run a stress test on the graphics card using a utility such as Furmark or Unigine Heaven to see if the GPU is handling the load correctly.
13. If none of these steps work, consider updating the motherboard BIOS or even replacing the motherboard.
