The BIOS (Basic Input/Output System) is responsible for managing the hardware components of your computer, and it’s possible that the graphics card may not be properly configured in the BIOS.
Access The Bios And Check If The Graphics Card Is Detected
To access the BIOS, restart your computer and look for a prompt to enter the BIOS setup. This prompt is usually displayed on the screen for a brief moment during the boot process. Once you’re in the BIOS, navigate to the section that displays information about your hardware devices.
Look for the graphics card in the list of detected devices. If the graphics card is not listed, it means that the BIOS is not detecting it. This could be due to a faulty connection or incompatible hardware. Check that the graphics card is securely inserted into the PCI-E slot and make sure all power cables are properly connected.
Ensure The Graphics Card Is Set As The Primary Display Adapter
If the graphics card is detected in the BIOS, but your computer still won’t start, you need to check if it’s set as the primary display adapter. The primary display adapter determines which device is used as the main display output.
To set the graphics card as the primary display adapter, navigate to the BIOS settings related to display options. Look for an option that allows you to select the primary display adapter and ensure that the graphics card is selected.
In some cases, the BIOS may have an option called “Init Display First” or something similar. This option determines the order in which the system initializes display devices. Make sure this option is set to the graphics card.
After making any changes in the BIOS, be sure to save and exit. Your computer will then restart, and hopefully, the new graphics card will be recognized, and your computer will start normally.
Check Hardware Compatibility
If your computer is not starting up after installing a new graphics card, the issue may be due to hardware compatibility. It is important to ensure that both the new graphics card and your existing components, such as the motherboard and power supply, are compatible with each other.
