I attached a FAT32 USB stick with the 1.10 BIOS file and used the UEFI Instant Flash tool to successfully downgrade BIOS A. I then added back my other RAM cards and successfully booted the system just like it was before. Problem solved, thanks for all of your suggestions!! |
That is great news ![Thumbs Up]( "Thumbs Up")
It sounds like the new BIOS version broke compatibility with your RAM, it would also explain why the backup failed, if the system detected memory errors it would not be able to properly complete and end up in a loop.
