How can I fix games crashing after installing a new GPU?

1. Make sure that your drivers are updated

If you’re experiencing crashes with a new GPU, your drivers may be outdated. There are several ways to update them, but the fastest would be using specialized driver updater software.

To make sure that everything goes smoothly and avoid any kind of GPU driver errors, be sure to use a complete driver update assistant that will solve your problems with just a couple of clicks, and we strongly recommend DriverFix. Follow these easy steps to safely update your drivers:

  1. Download and install DriverFix.

  2. Locate your graphics card driver, right-click it and choose Uninstall device.
  3. Check Remove driver software for this device if available and click on Uninstall.
  4. After doing that, install the latest drivers for your new graphics card.

A few users reported that switching to an older driver version fixed the problem for them, so you might want to try that as well.

3. Underclock your graphics card/RAM

If the games crash after installing a new GPU, your PC may not handle the current graphics card. One way to fix this problem is by underclocking your graphics card.

To do that, you need to use overclocking software that is compatible with your graphics card and reduces overclock values.

Some users suggest lowering the frequency by 100MHz since that might be able to fix the issue, so be sure to try that.

Others also suggested that you might be able to fix this problem by underclocking your RAM. To do that, follow these steps:

  1. Enter BIOS. To see how to do that, check our guide on accessing BIOS.
  2. Next, go to the Overclock section.
  3. Lower the RAM frequency. Some suggest using the default frequency for RAM.
  4. Save changes.

Remember that underclocking will slightly reduce your performance, but it might help fix the game crashes.

4. Turn off G-Sync

  1. Open the Nvidia Control Panel.
  2. Now go Setup G-SYNC in the left pane.
  3. In the right pane, uncheck Enable G-Sync and save changes.

Once you disable G-Sync, check if the problem is still there. If Nvidia Control Panel is not opening, our quick solutions will help you.

5. Check the power supply

You might have to check your power supply if the games crash after installing a new GPU. But, first, make sure that everything is connected correctly.

Next, you might want to test your power supply. Again, you can do that easily with specialized power supply testing software.

Lastly, be sure to check the power output. Your new graphics card might need more power; if that’s the case, you might have to upgrade your power supply.
