Whole server turning off suddently after booting my most important VM (downgraded the setup)

Hi !

Really a critical issue here. Until now my Unraid server was a strong powerful PC (i7-14700kf + RTX 4060) used for me to use a VM as my main PC. I did setup an important PC, everything worked well no issue. It was using the GPU Passthrough, 24Gb of RAM only for the VM etc.

But for personnal reasons, I need to downgrade my setup. I removed the GPU + CPU + MB + RAM for something more light (i7-10700 / No GPU / 8Gb of RAM). Changing the PC was fine, the server works well no issue. So i've tried to boot my VM (after removing the old passthrough stuff etc) and... No result (no post). So easy fix was to just create a new profile using the correct vdisk.

It worked fine. Until the VM passed the Windows loading screen. After that, the WHOLE server just shut down. No alert, no warning. Turns off. I don't really know the issue it should just move fine. For information, I don't need the power of before. I just need to access my internet browser and the file to prepare a migration planned next week. So nothing special will be launched.

I blamed the RAM but I had like 2Gb for the Unraid and 4Gb for the VM. Nothing else.

Really need an urgent help here.

Edit : Thrown 32Gb of RAM. Still not working. I could hold it a little longer but still turned off.

Edit 2 : Used a NON Unraid VM Windows. Let it run for 1 hour straight. No issue. Launched the VM. Passed the password => Unraid died.

It's really important for me to have a solution here.

Thanks !
