Hello,
Thanks for the alert. I am not sure why I was not notified of your post :)
The BIOS is fully updated which I wanted to check.
Looks like a Memory test is required.
I suggest you run a memory test for at least 8 passes, preferably overnight.

When the test is complete, post the Image (you can use your phone's camera).
