Description of Original Problem: My newly built PC keeps on restarting randomly. Sometimes, it will run for 6-10 hours without any issue. Then other times it will simply restart when I open an application (browser, tabs, etc.) or games and sometimes it just restarts at its will. Every time it restarts, the event logger logs the below errror:
"A fatal hardware error has occurred.
Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Cache Hierarchy Error Processor APIC ID: 11
The details view of this entry contains further information."
Troubleshooting: I have updated all the drivers. Deleted and reinstalled and updated all the drivers. Checked if the CPU fan is properly attached to the CPU, if GPU is properly attached, if RAMs are properly attached, and everything else. All of them seem perfectly fitted. Used various software to test CPU, GPU, RAM, etc. All came back with good results. Did memory test and DISM test. Both were successful without any error.
Thank you for your message. I literally tried almost everything and still facing the issue. Now, I am running my PC in clean boot. Will test it in clean boot for few days and see how it goes. Many people faced similar issue with 5700XT and Ryzen CPU combination. Not sure if it is the CPU or GPU. Many have changed the graphics card and many other underclocked their CPU/GPU and adjusted PSU voltage accordingly. I do not want to do either of these two. Don't know what I will finally do though.
A you running with your bios at defaults with XMP and PBO off. If not do so and see if that changes anything. If that doesn't help uninstall the AMD GPU driver and then for the sake of testing just let windows load its standard driver. See if that changes stability. Hopefully this can lead to you isolating the issue.
I will add that a lion share of the time that I have had problems that make a machine restart it comes back to memory issues. It is however very hard to say without some testing.
Also if you have not already. Boot with one stick of ram at a time and see if one is stable vs the other.
I met several threads on reddit with the same error. Most users had rx5700 or 5700xt. This issue cannot be memory related. I have tested my memory many times in stock, xmp and overclocking and all tests show 0 errors. Regardless, I bought new RAM on micron e-die, and crashes happen with the same frequency.
