I have a HP Z800 with dual Xeon CPUs that turns on, but does nothing after that. Removing the GPU and RAM gives no error code.. the only error I get is 3x beep when I remove the CPUs. I probed the bios with an oscilloscope and there is no activity at all, it basically gets never accessed.
Voltages seem to be all present, I dont see any shots on the board or anything visually that show some issue.
The workstation seem to have works fine till one day it just started with black screen and thats the situation I have at the moment.
I did reflash the bios just to rule that out.. but nothing.
I am honestly unsure what to test here... or how to identify issue?
My best guess would be that the PCH is dead...?
Any suggestions on what I could check is very welcome!!
Thanks!
ps: I will attack an image of the board.. its just an reference from the internet, but looks exactly the same.
