A graphics card is a computer component that handles the graphical data computation and displays this on the monitor. Most of the high end graphics card can render high definition images at an extremely fast rate making then an ideal choice for gamers. Although it is quite easy to install a graphics card on a desktop computer, there are instances when certain issues can occur. In this latest installment of our troubleshooting series we will tackle the graphics card not detected issue.

How To Fix Graphics Card Not Detected Issue

Before performing any of the recommended troubleshooting steps listed below it’s best to restart your computer first. This action refreshes the operating system and remove any corrupt temporary data that could be causing the problem.

There are several factors that can cause this particular problem ranging from a faulty driver to a BIOS setting issue. Listed below are the recommended troubleshooting steps you need to do to fix this problem.

Check  the graphics card installation

The first thing that you should do is to make sure that the graphics card is connected properly to the motherboard slot.

  • Turn off the computer. Make sure to unplug the power supply from the power source
  • Open the computer case
  • Remove the graphics card from the PCI slot. Reinsert the graphics card to the PCI-Express x16 slot carefully.
  • If the card requires additional power then connect it to the power supply cable.
  • Turn on the computer

Check if the graphics card not detected issue still occurs.

Check the BIOS setting

If your computer has an onboard graphics then you should try to disable this from BIOS. There are different ways to do this depending on the motherboard manufacturer but the steps listed below are generally what you will have to do.

  • Restart your computer. While the computer is running the POST look for a message indicating a key to press to access the “Setup” or “BIOS.” On most computers, the key to access the BIOS will either be “ESC,” “F1,” “F2,” “F10” or “DEL.”
  • Use the arrow keys on your keyboard to navigate your BIOS and use any instructions to change values. Find the menu item that closely matches “Integrated Peripherals” or “On-Board Devices.” The setting to disable the on-board graphics card may also be under the “Advanced” option. Highlight the appropriate menu item and press “Enter.”
  • Highlight the option that controls the on-board graphics card and press “Enter,” then press the appropriate key to select “Disable.” If your option allows you to enable an external video card, set that option to “Yes” or “Enable.” If your options for the video card are “PCI-Express” or “Integrated,” choose the type of slot in which you have installed your new video card. Press “Enter.”
  • Press “Esc” until you have backed out of all menus and are at the main BIOS screen. Select the option or press the appropriate function key to “Save and Exit.” Press “Enter” to confirm.

Set your graphics card as the default

This step applies to NVIDIA graphics cards.

  • Open Nvidia control panel. You can simply right click on your Desktop and select Nvidia Control Panel
  • Click 3D Settings
  • Select Manage 3D Settings from the left pane. It should be under 3D Settings
  • Select Program Settings tab
  • Select a program that you want to select your graphics card for. You can select the program from the drop down list in Select a program to customize section
  • Select High performance Nvidia processor from the drop down list in Select the preferred graphics processor for this program section
  • close the panel and try to run the program that has the Nvidia graphics card as the default device.

Check if the graphics card not detected issue still occurs.

Check the power supply

There are times when the problem is caused by the power supply not providing the correct amount of power. If you have a powerful graphics card and are using a low wattage power supply then this problem is most likely to occur. Try to use a different power supply, I recommend getting an 80+ true rated power supply from reputable brands such as EVGA, Seasonic, or Corsair just to name a few.

Update the motherboard BIOS

If you are using a new graphics card then this might not be compatible with your motherboard yet, especially if you are using an older generation motherboard. One quick way to fix this is to make sure that your motherboard BIOS is updated.
