check to see if any other appliance works in those sockets. If the socket works. It sounds like the power supply may have gone bad in the computer

a Few checks that might sound stupid.\n1) check all cables are secure\n2) when you boot do you hear more or less beeps than before and if yes the length of them.\n3) does the hard drive kick in\nif these all work then it sounds as if you monitor is up the creek

Sounds like you have a bug. Take your computer into a repairman (or repairwoman).

Does the thing power on?\nIf so then try replacing your graphics card with another AGP graphics card (just borrow one if you don’t have one spear).\nIf this works then it would seem that your graphics card is broken.\nIf this doesn’t work then try removing the AGP card and try adding a PCI card (again borrow one if you don’t have a spear).\nIf this fixes it then your AGP port is broken.\nIf not then you have probably fried your motherboard, this has happened to me before.\nJust replace the board.\n\n\n\n(EDIT)\n\nFollowing your recent additon to your question, I'm pritty sure that the motherboard is dead.. sorry.\n\n(EDIT2)\nafter removeing all the graphics cards does the onboard graphics work?\n\nalso, have u tried a diffent monitor??...

1.Please check the Cable connecting your computer.\n2.Please check the Internal Wiring ( if you can ) else call the service engineer he will be able to fix it.

something is fried in your laptop, most likely the internal power module. the clear signs are, the lcd and the hard disk get no power.\ntherefore you have no other choice than getting your laptop to repair.

Restart it. Maybe some program is not running at all. If it doesn't  work you need to see a technician.

Is there anything on the monitor when you turn it on or is it just completely black?\n\nIt could be a number of things. It could be your fan or your connection or maybe your RAM is damaged. Normally if your hard drive or memory dies, you would not be able to turn the computer on at all or you get a message on your monitor saying an error occurred trying to read your drive.\n\nI have an emachine too, I usually do my own fixes, but I would open the motherboard up and watch what the circuits are doing when you try to turn it on. If you had a short circuit from a power outage and you dont have a surge protector, then its possible it damaged your hard drive or your memory.\n\nEDIT: Yes, 4 years is usually the lifetime of a desktop computer, especially an emachine. You will have to take it to the technician and figure out whats wrong with it because I read the other DETAILS and it sounds like your hard drive has fried or some part of your motherboard has been damaged. You will need to install a new hard drive. Normally when your hard drive gets fried, the data is not retrievable. A technician can tell you whether or not they can save the data, but it will cost you A LOT trying to recover all your data from your hard drive. You should always backup any important data every few months to a CD-RW in case this stuff happens. A computers lifetime is very random, but 4 years is usually when something goes wrong.

First of all if you've checked that the monitor is still plugged to electricity and won't work, I recommend you to take it to a specialist, so it will give you a solution.

If you have used a power suply tester and verified that that power supply in the current computer is OK, then unplug and replug in every connection to that motherboard. Try restarting the PC and see if the PC reboots up. If you have a second power supply then take the other one out and hook that one up. If you still cannot get the PC to start up or at least get the BIOS start up screen there is no sence testing the motherboard because my friend is fried. Consider replacing it.

make sure your computer is plugged in!!

Your power or data cables may not be plugged in properly.  Or the CD drive is defective.  Does the drive light come on?

If all you get is a black screen then how do you know that your PC doesn't boot?  It may be booting.  Check cable connections including power.  Is monitor turned on?  If all checks out then check computers setup using appropiate F Key (varies depending on brand and model, see manual).  If still black then try another monitor.  If problem persists then the problem may be your card but most new PCs have the video card integrated on Motherboard and if that is your case, then more than likely, depending on age of PC, it is better getting a new PC then fixing it.

unplug it and plug it in again.  if this doesn't work, you may need a new power supply.  if you do need to purchase something, antec is good.

HOLD ON GUYS!!!\nbefore you start ripping your computer apart, and running out to buy a new video card try the simple things first.\na) are all cables connected correctly and securely.\nb) are all power cables connected. etc.\nc) did you try the reset button\nd) try a different monitor on your computer, and see if your monitor will work on another computer.\nif none of those things work and you are comfortable opening up your computer, then do so and check the connections.

need more info than that to diagnose.  make sure your cables are plugged in tightly?  is the jumpers on the hard drive on the correct pins?  can you hear it booting up. when does it stop?\ntoo many variables

This sounds as if your power supply on the PC itself went bad.  Especially if you have checked all your power connections, and you are still on getting power to your system.  \n\nyou may need to contact E machines and see if your system is stll under any warranty.  If you have any Geek friends, have them check it out to make sure its the power supply, and not the motherboard, memory, and/or processor.
