k, heres a update.. on the problem.. i called Best buy (geek squad) if u dont kno what that is.. they fix computers etc..  told them about the Light coming on around the power button.. and they said that indicates nothing is wrong with the power supply or cpu.. which totally negates what all of YALL are saying.. i Dont think there right.. i trust people that have had experience with this problem over the foriegn outsourcing guy they hired to run customer SUPPORT.. i LOOKED inside the comp when it was plugged in... the light ring around the power button is on.. but no lights on the cpu are on...(which im not sure if it even has lights on the cpu, my old comp does.) also i tried hooking up power supplys from old comps on to it.. i dont think i hooked them up right.... Can anyone direct me to a diagram or chart on how to hook up the power supply and stuff correctly.. i think i messed with the LED cables on accident and i need to place them in the right spotHello rippla420,

I don't know if you read all of the posts, but Geek Squad basically just told you what we told you. It's either the Power Supply or it's the CPU. Chances are, however, that it's the Power Supply.

Before you replace it, however, check the back of the computer. Where the plug goes in, is there a switch? If there is, what is it set on?

This switch is used to tell the power supply what kind of electricity is going into the machine. In Europe, they use a different voltage (somewhere around 220 volts) than we do in the United States (the setting is usually 115, 120, or 125 for USA power).

You may need a small screwdriver to flip the switch, as often they are receded into the supply to prevent accidentally flipping it. BE CAREFUL NOT TO PUT THE SCREWDRIVER- OR ANYTHING- INTO THE POWER SUPPLY ITSELF! They hold very high voltage capacitors WHICH CAN KILL YOU with the electricity they store.

If you do need to switch it, unplug the machine, flip the switch and wait a 5-30 minutes for some of the electricity in the PSU to dissipate. Then plug the machine back in and start it up.

If this doesn't work, please POST again and I will try to help you with making sure the Power Supply is hooked up correctly. oh no they are right there is nothing wrong with the psu there is a way to test it using a paperclip (google test psu papeclip or something along that LINES) which is relatively safe if you don't touch the paper clip or start jamming metal things in there. Geek-9pm said it best it's an emachines and if the swith lights up the psu hasn't failed.

A psu lasting over 6 years is definately not unheard of the switch failing on the other hand sounds like the more likely culprit to me. Take a loot at the type of power switch you have go down to you're local electronics store and get a new one that supports the same volt and amps and give that a shot.
