Question about PC Desktops
There are many possible reasons for this. You best bet for troubleshooting is to get the computer to a minimal configuration. Do this by removing all add-in cards, unplugging all drives (CD, Hard drive, Floppy), remove all memory modules but one. If the PC boots then add one device at a time until you find the one that is causing the problem. If it doesn't boot in it's minimal configuration then either the RAM you left in, the CPU, motherboard, or power supply is faulty. I would bet that it's either the RAM (try a different module), or the motherboard. If it's not the RAM (no modules work), then your best bet is to test with a known good power supply. If that still doesn't work then it's either your CPU or motherboard, most likely the motherboard, CPUs don't fail very often. Good luck!

you plug in the power cord is there any lights whatsoever on the laptop, where
the plug goes in or on the AC Adapter of the power cord?
When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the computer is trying to boot or may have booted, but the screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.
your memory is bad or the memory slot is bad.
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.
