How do I troubleshoot a black screen after installing a new graphics card?

  • Updated

Experiencing a black screen after installing a new graphics card can be frustrating, but here are steps to diagnose and resolve the issue:

Check Your Power Supply Unit (PSU)

  1. Verify PSU Wattage:

    • Determine your system’s PSU wattage by checking the sticker on the PSU itself for its maximum output.

    • Visit www.visiontek.com and search for your graphics card’s 900XXX P/N.

      • On the product webpage, click on “System Requirements” to find the graphics card’s recommended PSU wattage.

    • If your current PSU wattage does not meet or exceed the graphics card’s recommendation, you will likely need to upgrade your PSU to support the new graphics card.

    • Contact your system manufacturer for guidance on compatible PSU upgrades that meet or exceed the recommended wattage.

Checking Your BIOS

  1. Accessing BIOS:

    • Shut down your system and remove the new graphics card.

    • Connect your monitor to the onboard graphics output or use a known working graphics card.

    • Boot into your system’s BIOS following your system manufacturer’s instructions or consulting your motherboard manual.

      • Note down the BIOS version currently in use.
      • Note: Only access BIOS if you are familiar with its operation.

    • VisionTek does not provide support for navigating, modifying, or updating BIOS settings. Contact your system manufacturer for assistance in locating and installing the latest BIOS update.

Testing the Graphics Card in Another System

  1. Transfer the Graphics Card:

    • Shut down your system and remove the graphics card.

    • Install the graphics card into another compatible system (if available).

    • Repeat the steps above to check the PSU compatibility and BIOS settings in the alternative system.

    • If the graphics card continues to display no output in the second system, contact support@visiontek.com or your vendor directly to initiate an RMA (Return Merchandise Authorization) process for further assistance.
