Hi EJ_Franckowiak,

The error that you are getting seems the Central Processing Unit (CPU) has detected an error in the system or received an erroneous instruction from a system component.

The workaround for this issue is the following: Double check if your system manufacturer released a newer BIOS and drivers for your computer and update the system.

Intel has a tool to verify how the processor is working called: Intel® Processor Diagnostic Tool

https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool

It is a stress test and your processor is old now. The tool might work on your system.

Hi EJ_Franckowiak,

I am following up your machine check error. In my previous email, I suggest you double check if newer BIOS and drivers were available at your system manufacturer. Additionally, to this troubleshooting, double check if all the memory modules are properly seated on the slots.
