Lenovo Thinkcentre M910Q blank screen (sh.itjust.works)

I use a M910Q with an engenering sample i9 cpu as my home server

After some seconds or minutes after the boot the screen blanks and the machine doesn't seem to have anything running inside

So, if I'm loading something with graphical interface it can show the desktop, sometimes I can use it, but some time after the issue appears

i tried changing the drives, the ram, booting from USB, the problem persists

i noticed that if I change some CPU parameters in the bios the behavior changes. Something like power profiles, and turning off "turbo" which shouldn't work with an es-i9

So my guess right now is that it blanks the screen when it hits some load, but I didn't check it properly. And it doesn't look like I ever encountered anything before.

Any ideas how can I track the problem without just buying everything new?

Thank you

Does it work with a regular CPU?

What are you running? Windows, Linux, BSD, TempleOS?

i don't have any other CPU to check, and this CPU worked well before

I'm use nixos, btw

If it worked well before, what changed?
