I have recently rebuild my Grandfather's old computer. Unfortunatly I did not bother to boot it up before "messing" with it, so I have no idea if the problem was created through transport of simply by y fault.
The problem is: the computer will not start up, as in it looks like there is no power reaching the computer.
However, the power cord was taken from another computer since I do not have the original, I assumed these things were standart but if it is not the case, it could be the problem.
Thanks in advance.
Edit: The things I plugged back in are PCI cards (Wireless card, USB ports) and in some other bigger slot, sound card.
