Argggg….Due to the fans starting really soon after boot, wanted to change the thermal paste, so disassembled it. Was very difficult to remove the board. It was stuck to the heat sink, was careful though i had to force and it came with a "clok" noise… No apparent damage on the board/CPU… so cleaned up the old thermal paste on heat sink and CPU, and replaced it with some ArticSilver paste. re-assembled it. no boot, nothing … only the cap lock key lights when pressed, and the power plug lights green…

 
So i suppose i've damaged the board… Stupid Me. Well i'm p… off, it's a beautiful 1 Ghz (was, now 0 Ghz…) Titanium, in mint condition. 
 
Now have to find a board.
 
(PS, sorry for coming crying here but i know you know what it is…)
