If we look at post #1 we can see that pushkar mentioned some corrosion/residue on the pins on the processor. He mentioned that this could be wiped clean (one pin at a time).
Normal chemical reaction corrosion will form a lumpy coating on metal parts. A sticky residue makes me wonder if it could be a case of excessive thermal compound that got into the socket?
The fact that the black screen occurs under any type of processor load points to a bad CPU (or motherboard-socket). My problem with that is that a CPU error will normally end with a shutdown or restart, not just the loss of video. There seems to be a missing piece to this puzzle.
Just thinking out loud.....
