hello i just received this Computer with intentions of trying out a MAC computer for the first time. i was told by the person i bought it from that it posts but has no operating system and hangs at a flashing folder.. i figured that would be a easy fix. well i bring it home and it doesn't display any video at all.. it chimes, and the light is steady on the front.. but that is the extent of it's functions. after a few minutes i notice the fans slowly start increasing their speed. well i tried different ram. tried re-seating the graphics card. tried resetting the PNU i also tasted the battery to see if it was holding a charge and it didn't taste like it.. so i put it in my 3.7v lithium battery charger for several minutes.. after that it did test at 3.6v. frustrated i unplugged everything and looked around closer.. i noticed that at the very top between the motherboard and cd rom there was some corrosion on the inside of the case.. i assumed maybe there was some on the bottom of the motherboard also and proceeded to disassemble everything. i got the cpu removed and noticed a whole bunch more at the bottom of the board and on top of the power supply.. is this the point of no return or is it possible to clean away the corrosion? did the liquid cooling solution leak out? is it possible to replenish it?
