Maybe your memory is bad or the memory slot is bad.
Remove the Power Cord, Open the Case and remove one of the
memory chips. Set the chip aside then try rebooting the computer.
If it boots, then you know the memory chip you set aside is bad so mark an x on
it with an ink pen. If it fails to boot then move the chip to the next
memory slot and try rebooting. If it fails take the chip out and set it
aside, then put the other chip in and try booting it in both slots. If it
boots, just to verify that the chip set aside is bad, mark an x on it and put
it into the open memory chip slot and try booting.
