You’re all geared up and ready to play your favorite computer game. But then you get this error message:

“No suitable graphics card found.” or

“Unable to create the graphics device.”

That’s such a let-down since the graphics card is vital to generating images on your display.

But worry not. You can get things back to normal in a few minutes by applying one or more of the following fixes (they work in all Windows versions, including Windows 7, 8 and 10).

Option 1: Delete Your Game’s Config.dat File

The problem of your graphics card error could have to do with the settings of your computer game.

Here’s how you can fix that.

You’ll need to delete the game’s config.dat file. This is a file created by the manufacturer to store settings chosen by you using the game’s settings menu. Removing the file won’t affect your game. It will only eliminate the default settings that are keeping the game from detecting the graphics card. When you start playing the game, it will again create a new config.dat file.

The config.dat file can be found through this file path: Documents > My Games > NameOfTheGame.

Follow these steps to delete that file:

  1. Locate the config.dat file of your game.
  2. Right-click on the file and select Delete. Then click Yes.
  3. Restart your PC.

Once you open your game, the problem should be sorted.

If not, the issue could be more than your game’s settings. Try the following options.

Option 2: Restart Your PC

This fix works if you already have the graphics card in your computer but it just hasn’t been detected by the system. Hence, restarting your computer will cause the system to check through all installed hardware and update itself on start-up.

It’s a simple process:

  1. Click on the restart option on the Windows Start page.
  2. Alternatively, you can shut down your PC and, when it’s shut down, you can check whether the graphics card is properly inserted.
  3. When your PC restarts or you turn it on again, check if the computer game now works without a hitch.

When you shut down your PC, you may find that you don’t have a graphics card inserted.

So, you may be wondering, “How to find a suitable graphics card for my PC?” The best way to do so is to check with your PC manufacturer for recommended hardware compatible with your model.

If you still get the error message, it’s time to try the next option.

Option 3: Update Your Computer’s Graphics Card Driver

If your graphics card hardware is inserted and you’re still getting the error message, the issue could be missing or outdated graphics card drivers.

In fact, it may be an outdated driver for another piece of hardware that’s also affecting the operation of your graphics card. Wrong/obsolete drivers can cause system conflicts that affect other components in your PC. Therefore, you need to update not only the graphics card driver but also all the drivers in your PC.

Doing that manually will take time and involve a lot of work searching for the right, safe and up-to-date drivers compatible with multiple components in your PC.


Resolve PC Issues with Driver Updater

Unstable PC performance is often caused by outdated or corrupt drivers. Auslogics Driver Updater diagnoses driver issues and lets you update old drivers all at once or one at a time to get your PC running smoother

If you cannot resolve the
problem yourself, you can
ask our certified PC technicians for immediate assistance in the chat right on this page.

Hence, the best option is doing it automatically using effective driver updater software, such as Auslogics Driver Updater.

Auslogics Driver Updater scans for all missing or outdated drivers on your PC and updates them in one click.

Most importantly, the software only installs official driver versions compatible with your specific device model. And it backs up your system before updating the drivers, so you can conveniently reverse any changes that you don’t like.

Restart your PC after updating all your drivers and check if your computer game is working.

If it doesn’t work, the issue is probably not related to your system drivers. The next option might sort out this problem.

Option 4: Change the Display Resolution and Use a Borderless Window

You may be wondering, “How does changing display resolution help?” Or what is the point of a borderless window?

This option might seem mundane, but it can have an impact on your situation.

The resolution of your display affects the amount of work your graphics card has to do. A full resolution will put more load on your graphics card, compared to medium or low resolutions. If your graphics card is not powerful enough, it might not manage quite well on a high resolution.

Therefore, it’s better to opt for a medium or lower resolution.

The size of the window for your computer game also impacts the performance of your graphics card.

If you’ve set up the game on a full screen, this exerts exclusive access to your graphics card (GPU). That gives the display adapter a more massive load in managing such issues as resolution switching and resource management.

Hence, using a borderless window will be more efficient than going full-screen.

A borderless window is merely a regular window, with the window chrome disabled. That means it doesn’t exert as much load on your display adapter as a full-screen mode.

You might have already noticed that many games act oddly and even crash when set to full screen. That’s because they don’t handle the alt-tab quite well. Hence, you’ll find a problem when trying to use alt-tab to check on your game FAQs or chat on Discord.

If that doesn’t work, try this final option.

Option 5: Install Microsoft .NET Framework

Many PC games require the Microsoft .NET Framework to facilitate multiple functionalities. You may not have the right version of the .NET framework. Therefore, you should check on Microsoft’s website, download and install the appropriate .NET framework.

While you’re at it, you should check if the manufacturer has new updates for your game. There could be some fixes for bugs that have just recently been identified.

This should fix your problem conclusively.
