  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.

Few users reported that switching to an older version of the driver 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, perhaps your PC can’t 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 reduce overclock values.

Some users are suggesting 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 how to access BIOS.
  2. Go to the Overclock section.
  3. Lower the RAM frequency. Some are suggesting using the default frequency for RAM.
  4. Save changes.

Keep in mind 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 definitely help you out.

5. Check the power supply

If the games crash after installing a new GPU, you might have to check your power supply. First, make sure that everything is properly connected.

Next, you might want to test your power supply. 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, and if that’s the case, you might have to upgrade your power supply.
