Look at the motherboard (mobo). Failure of motherboards is usually due to breaking capacitors. A few years ago a capacitor company stole the "recipe" for making capacitors from another company and tried to make their own, unfortunately they did not get the ingredients right and the capacitors started breaking after 2-3 years of use. They sold these capacitors at very cheap prices and a lot of computer companies and power supply makers bought them. This is easy to diagnose. Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything.
You could also try to change out the power supply if you can find another one that fits it.

Do you hear anything during startup, beeps, fans or drives spinning, lights on the front or back of computer flashing or lit up? Do you hear the Windows starting sound?
Let us know more then we can troubleshoot better. It is starting to sound like 1 of 3 things, Power supply, Video card or motherboard.
Situation #1: If you get a blank screen and no sounds or movement it either indicates that the power supply unit (PSU) has failed or something on the motherboard has failed, preventing normal startup.
Situation #2: If you get sounds and lights but nothing on the screen then it indicates a failed or loose video card.
Always try a different power outlet that you know is working. (Eliminate the easy stuff first!)
If it is out of warranty, Try opening up the case, with the power off, of course. If you have Sit #2 and have a video card that you can reseat try that.
Also take the time to inspect the capacitors on the motherboard (they look like tiny soda cans) and check for tops that are bulging, swelling or leaking anything. Capacitors should be perfectly flat on top. If you find these then your motherboard is bad (well technically the capacitors on your motherboard are bad). The caps will need replacing to fix (not a job for an amatuer). If it passes the visual inspection then it may just be your power supply is bad. Notice that a bad PSU does not mean you are getting no power, just not enough to start and run the computer.

Steady Amber Power LED generally indicative of a failed MB. Remove all Memory, Expansion Cards, peripheral items, if still same, replace the motherboard. If you get a Green LED with jusr RAM in system, then an expansion card or peripheral might be the issue. 95% sure it is mothebroard
