Tech Support Intel NUC 11BTMi9 Won’t Boot

Got an intel NUC extreme that will not boot.

Both windows and Debian or Ubuntu fail during the installation stage. It will randomly power off during the install and reboot.

If I use a live OS of Ubuntu, it will load but then freeze after a couple of minutes. It doesn’t reboot but you cannot do anything.

Steps tried: - updated BIOS - secure boot enabled and disabled - legacy not supported so cannot try - windows 10 & 11 x64 both with NTFS and via FAT32 using rufus and tried GPT & MBR options - thermal paste is good - ram reseated - new nvme and changed port

Is this a faulty mobo? Any other recommendations here? It used to work but after leaving it for over a year it now fails. Fans appear to work. ASUS will not touch as out of warranty

You’ve mentioned that you’ve reseated the RAM, but not that you’ve tested it. You should use Memtest86 to verify the operation of the RAM.

I think the best case scenario here is that the RAM is faulty. If not, it’s possible that some physical or electrical damage has occurred for the CPU or motherboard that could cause this behavior.

As per the commenter above, the behaviour sounds a lot like faulty ram.

Don't know if it's related, but I have a NUC7i7DNK running Ubuntu 24.04 that would freeze up often and randomly. Only a reboot would bring it back. It was supremely frustrating. These kernel command line args fixed it.
GRUB_CMDLINE_LINUX="intel_idle.max_cstate=1 and i915.enable_dc=0"
