Troubleshooting Video Cards

  1. Try to re-install the drivers – It is the most important step of your troubleshooting process. It solves ninety percent of the problems. If the problem still persists, move on to Step 2.
  2. Restart your PC – It also sometimes solves the problem, with me having no idea how!
  3. Underclock your GPU – You must have heard about overclocking, but underclocking also helps at times when your GPU is overheating. Most vendors offer utilities to do this.
  4. Open Up – When nothing works, just open up your cabinet. Remove your GPU and reinstall it. Check for any wires mingling with the fan. Tighten the screws. Most of the time, it works out!
If no method works, try booting in from the motherboard chipset and see if the PC boots. If it does, then unfortunately I have to say that the GPU of yours has gone kaput. Get a new one or if it is under the warranty period, get a definite replacement. Because the gaming mustn’t stop, right?
