No Liquid damage.
Tried the ram slots with multiple sticks of good ram. Most of the times only 3 beeps. Sometimes it will start with the bottom slot only but on boot kernel panic followed by restart.
First conclusion was that both slots went bad (came across a case like this some time ago).
I was thinking that this looks a bit different that any bad ram slot case I saw before so maybe it is not the ram slot but something else.
Checked PP0V75_S0_DDRVTT. It is 0.75v.
Anything else to check?
