8 steps to fix apc_index_mismatch BSOD like a pro

4. Check your drivers

1. If you cannot access Windows 10, enter the Safe Mode.
2. Start the Device Manager (press Windows Key + X and choose Device Manager from the list).
   
3. Once the Device Manager starts, locate the newly installed device. (If you see an Unknown Device or any device with a yellow triangle, you’ll need to update its drivers.)
4. Right-click the device and choose Update driver. In addition, you can also download the latest drivers online.
   

If you wish to keep your Windows 10 PC error-free, we strongly advise that you update all your drivers.

Updating drivers manually can be a long process, but you can use third-party tools to update all your drivers with just a single click.

Some of the most common Windows errors and bugs are a result of old or incompatible drivers. The lack of an up-to-date system can lead to lag, system errors or even BSoDs.
To avoid these types of problems, you can use an automatic tool that will find, download, and install the right driver version on your Windows PC in 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. Launch DriverFix.
3. Wait for DriverFix to detect all your faulty drivers.
4. DriverFix will now show you all the drivers that have issues, and you just need to select the ones you’d liked fixed.
5. Wait for DriverFix to download and install the newest drivers.
6. Restart your PC for the changes to take effect.

5. Uninstall the DisplayLink driver

1. Open Control Panel and navigate to Programs and Features.
   
2. Locate DisplayLink Core software on the list and uninstall it.
3. After you’ve uninstalled it, restart your computer.

In order to completely remove the DisplayLink driver, you need to download and run DisplayLink Installation Cleaner.

After using this software, the DisplayLink driver should be completely removed and the apc_index_mismatcherror should be fixed.

DisplayLink is useful when you have an additional monitor, but unfortunately, it seems that there are certain issues with the DisplayLink driver and Windows 10.

6. Change your RAM frequency

This is an advanced solution, and by performing it you might cause damage to your PC.

Changing the RAM frequency might lead to system instability if not done properly, so bear in mind that you’re doing this at your own risk.

If your motherboard cannot handle the frequency of your RAM, it’s advised that you remove any overclock settings that you have.

Alternatively, you can underclock your RAM so it can match your motherboard frequency.

Test your system to detect and prevent overclocking settings with these amazing tools.

7. Disable Virtualization in BIOS

1. Enter BIOS. (To do that on your PC, you need to press Del or F2 during the boot sequence.)
2. Once you enter BIOS, you need to find and disable the Virtualization feature. (To see how to locate this feature, you might want to check your motherboard manual for detailed instructions.)

After disabling this feature, check if the problem is resolved. If you don’t have a Virtualization feature available in BIOS, you can skip this solution entirely.

8. Check your hardware

As previously mentioned, BSOD errors can appear due to faulty hardware.

According to few users, the problem was caused by a faulty touchpad on their laptop, and after replacing the touchpad the apc_index_mismatch error was resolved.

If your device is still under warranty, you might want to consider taking it to the official repair shop for a hardware replacement.

9. Remove interfering software

Software such as LogMeIn can cause the error, therefore it’s advised that you update it or remove it from your PC.

In addition to LogMeIn, certain antivirus software, most notably Norton or Avast can cause this issue to occur.

If you’re using any of these antivirus programs, we urge you to remove them by using a dedicated uninstaller such as IObit Uninstaller Pro, to make sure all related files are deleted.

Also, you might want to consider switching to different antivirus software. There are many great antivirus tools that offer great protection and they are fully compatible with Windows 10.
