Recently, I had to deal with an issue where a video card was underperforming. This was an odd issue and was really the first time I have seen this particular problem. I did quite a bit upfront research on this and it turns out there are multiple reasons why a video card may be running slow. Let’s get right into the causes and solutions for a video card that is not performing as expected.

Overheating Issue

This is one of the most common reasons why a video card may underperform. One last thing to check is if your video card is overheating. This is especially true if you have been using the same video card for awhile. After months or even years of use, the card gets dirty and dusty, and the thermal paste that helps dissipate the heat break down. Extreme overheating issues can cause blue screens and even damage to the card. However, even minor overheating can keep the card from running at maximum efficiency. If you believe this is the cause, cleaning the dust off your video card and reapplying thermal paste should help. As part of this, you may want to give your whole computer case a good cleaning if you can as that can make a big difference as well.

Driver Software Not Up To Date

Driver software for video cards is updated quite often. If your video card is underperforming, it is worth updating the driver software for your particular card. Even if this doesn’t fix the issue, having the latest drivers is beneficial for many reasons. I would recommend downloading the newest drivers directly from your video card manufacturer’s website. This is generally a pretty quick and easy task, so I would definitely try this first or second.

Video Card Clock Manually Set Below Standard

This is another not so obvious thing to look at. Nowadays, most video card driver software allows for you to lower the clock speeds below standard. Alternatively, the video card speeds can often be changed in the BIOS as well.  So, one of the first things to look at is whether or not the clock has been manually lowered in the BIOS or in the video card driver software.

Video Card Not Seated or Plugged in Correctly

This is another simple thing to check. If your card isn’t seated correctly or if it isn’t getting enough power, it could cause issues. Try re-seating your card. Also, while you are in your case, check to make sure that all power connections are properly connected and secure. Before opening up your computer case, make sure to shut down your PC and unplug the main power for safety reasons.

BIOS is not up to date

Another reason why the video card may be underperforming is that your BIOS is not up to date. If you have gotten to this part of the guide and your video card is still slow, you can try updating the BIOS as this may help fix this issue. Also, keeping your BIOS up to date can also help to fix other issues such as compatibility problems.

Virus or Malware

One more thing to check for is a virus or malware. It is pretty unlikely that virus would directly target your video card. However, if you have a virus, your whole PC could be underperforming. So, running a virus and malware scan can help your performance in general. Checking for malware is something you will want to do regularly with or without any performance issues.

Overall, there are a number of reasons why a video card may be underperforming. By checking the possible issues above, you should be able to get your card running at top speeds again.
