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

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.

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

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.
