I can't get my pc to turn on. I have unplugged, waited, tried another outlet etc. This started approximately a week ago. After several tries, it did come on, and I was able to use it for about 4 days. I was able to turn it on/off without difficulty. Suddenly, when I went to power it up again, nothing happened. What might the problem be? It is approximately 6 years old.
I researched this a bit more. Apparently, changing out the power supply may not solve the problem. Approximately 70% of the time, with an E machine, when the power supply dies, it also takes the board with it. There is no way of knowing if the board is bad, unless the power supply is replaced ($125.00). Does this sound familiar to anyone else? Complete repair (including installing Windows on the new board) would run about 350.00. This is the Midwest...not sure what other parts of the country run.

test the power cord+ outlet for faulty with multimeter. However if this things are o.k You must test the power supply pack for faulty, test the 5 vdc+12vdc, etc and see if there are Faulty. and replace. Please tight cable or connector inside. Test too the small battery for CMOS for +3vdc and replace.
Need more info, Give as much detail as you can. What happens when you push the on/off button? Fan spin? LED's Blink? Any thing on the screen? Sound? Does the computer try to start and a second later shut down? Check the power cord, check the AC outlet? Is it on a UPS? Try AC outlet? Can you get to BIOS or Boot Menu? ETC.
Sounds more like a power supply problem. First test the on/off switch by tracing the wires to where it connects to the mother board. The plug is usually marked "pwr sw" . Unplug the wire from the board & short out the 2 pins where the switch was plugged in using a small screw driver or any other conductive material. If the pc still fails to turn on, try replacing the power supply. Best wishes, Graemevm
You can try unplugging the PC, removing the RAM and re-seating it. It could also be a power supply issue, either too much for it to handle or it's not functioning correctly. My first suggestion would be unplugging hardware that's not needed for a week or so and see if it keeps happening with only the HDD plugged in. If it doesn't continue plug one thing in at a time until you find the culprit... although because it does run for a bit when you have the so called culprit, unplug it and plug something in its place, if it continues then you may have over powered your power supply and need to get something a bit larger.
You may also have issues with the PC over heating or fans not running correctly, make sure to check these items while your PC is turned on. (please be careful).
Make sure the power cord is securly plugged into the Power Supply Unit in the back of the PC and also in the wall outlet. Look for a switch by the cord plug on the pc that will have a straight line and a circle on it. Make sure it's switched to the ON position (straight line). Try and turn on your pc.
If this does not work still, try a different AC outlet on another wall or in another room. Also try a different power cord for the PC. If none of these work and your machine will still not start up or you don't hear any fans going when you press the button, it might be a bad Power Supply Unit (PSU). I have seen PSU's blow out just by plugging or unplugging the power cord because it can create a spark. If you have a bad PSU, you will need to contact someone local to replace it or you can take your unit to a Best Buy or local computer store and have them give you a price on a new PSU.
The green light is most likely your lan card/port. If the cord/outlet are sparking when you plug it in, I would say try plugging something else into that socket, if you get the same spark, I'd call an electrician. Also try plugging the pc into a different outlet. As far as the computer, if its not the outlet then it is the power supply, your motherboard may be fried in the process but if this isn't an issue with that outlet, then you should take it in to a shop.
If you cant see or heard any boot up sounds, fans and especially if you dont see any power or green led lights at all ;
If your power cord is plugged into a power strip or surge protector, power cycle your strip or surge protector by turning off and on.
If power outlet has a wall switch make sure its on
Check that your power cable is securely plug in to both ends
Check that at the back of computer, specifically on the back of the power supply unit that the switch is on "1" position and NOT on the "0" position ( 1 is "ON" , 0 is "OFF" )
Check that the power outlet is not damaged by pluging in another good known device (such as a blowdryer, shaver, lamp, radio, etc, etc) to see if its the power outlet or not.
Can you see power or green led lights and hear the fan on but no display ? If this is the case , check your monitor connection at both ends. If they are secured open up your case and see if you can smell any burnt smell or check that all cards especially video cards are properly seated.
