CompHQ Video Card (GPU) Troubleshooting Guide

Here are a few simple things to try to troubleshoot your video card or video issues.

  • Use the Correct Port: Check to make sure your monitor is receiving display from the output on the Video Card. If you are using the display output from your motherboard while you have a Video Card installed, you likely will not get any video.


  • Check Cables: Check to make sure your cord (HDMI, DP, DVI) is functional. Try one of the cords from your television if you don't have any extra laying around.
  • Seated with power: Make sure the Video Card is seated properly in the correct slot and is receiving power from the Power Supply (PSU). Additionally, consult the user manual or look online to make sure you’re using the correct PCI slot.
  • Drivers (Software): Install the latest drivers for your specific model and make sure to uninstall any old display drivers. You can use this link for Nvidia GPU drivers http://www.nvidia.com/Download/index.aspx or typing “Model #” with “Driver” into a search engine will also work.
  • Other Hardware: If you have changed to a different Motherboard, CPU, RAM, HDD/SSD, Monitor or other hardware, make sure you also rule out that those aren’t the root of any issues.
  • Insufficient Power: Research the Video card to make sure that your Power Supply (PSU) can supply enough power to run it. The PSU may not be suppling enough power based on how demanding the Video Card is.
