Ok, if someone had brought it to me with a plea to see if it lives.
unplug everything, remove expansion cards, take out motherboard.
Remove the CPU, take off the cooler, clean off the old heatsink slime, replace with new. refit CPU and cooler (take care with anti static precautions and the pins on the CPU.
Clean the earth plane pads round the mounting holes on the back of the motherboard, clean the standoffs in the case, refit motherboard.
fit one stick of memory in one dimm slot, plug in keyboard monitor and your boot drive.
test.
(the earth plane pads is a common issue on older machines and it may explain why plugging in fans changes stuff, - spurious earth paths)
