Hello,

A Machine Check Exception (MCE) is a type of hardware error that occurs when the computer’s central processing unit (CPU) detects a problem with the system’s hardware. The “Cache Hierarchy Error” indicates that the issue is related to the CPU’s internal caches, which are memory layers that store data for quick access.

You can follow these steps:

1、Check your motherboard manufacturer’s website for updates to the BIOS/UEFI. An update could resolve compatibility issues that cause these types of errors.

2、Make sure that all your drivers, especially the chipset and graphics drivers, are up to date. You can download the latest drivers from your hardware manufacturer’s website.

3、Overheating can cause hardware to malfunction. Ensure that your CPU cooler is properly seated and functioning.

4、Use system diagnostic tools to check for hardware issues.

5、Run a memory test using MemTest86 or Windows Memory Diagnostic to check for RAM issues. Faulty RAM can also cause these types of errors.

6、Perform a clean boot
