Check to see if you have bad Electrolytic Capacitors, on the motherboard of your computer. Specifically the one's used in the voltage regulator circuit.
To explain:
A) Electrolytic Capacitor
An Electrolytic Capacitor slowly builds up a charge, then releases it all at once. (One example, is when this electronic component is used in a flash unit for a camera)
Think of a large swimming pool being filled up by a garden hose, then one wall of the pool is taken down all at once.
The Electrolytic Capacitors used in an eMachines EL 1600, are Radial Aluminum Electrolytic Capacitors.
In the above article link, scroll down to the heading, Construction.
Taking a Radial Aluminum Electrolytic Capacitor for an example, (There are many designs of Capacitors. Form hereon in, all reference to capacitors will be of the Radial Aluminum Electrolytic Capacitor );
The Radial Aluminum Electrolytic Capacitor's construction, is essentially an aluminum 'Coke' can, with two strips of aluminum foil, and a strip of paper soaked with Electrolytic paste, rolled up, and placed inside the 'can'.
1) One strip is a thin aluminum foil. This is the Conducting strip, and the Positive lead is connected to this strip of metal.
2) The other strip of aluminum foil has a non-conducting medium applied to it, and is the Non-Conducting strip. The Negative lead is connected to this strip of metal.
3) The paper-like strip is soaked with Electrolytic Paste, and placed in-between the two metal strips. Then all three strips are rolled up tightly, and inserted into the can-like shape of the capacitor's aluminum case.
At the bottom of the capacitor's case is a seal. A round, flat, synthetic rubber disk, called a 'Bung'.
At the top of the capacitor's case is another seal, which goes around a flat aluminum metal disk. This disk has a shape etched part way into it. The shape is usually a K, or X.
After a given time the Electrolytic Paste breaks down. It forms a gas, (Hydrogen Gas), and the gas expands inside the case of the capacitor.
The gas compromises, (Breaks), the seals at the top, and/or bottom. It can also split the K, or X shape of the disk at the top.
This allows paste loss. The gas pushes the paste out. (It oozes out) So much paste loss, and the capacitor operates at a weakened state. Too much paste loss, and the capacitor fails.
Part of what the motherboard Voltage Regulator Circuit does, is to regulate power to the Processor.
A Processor must have a steady, 'Clean', supply of voltage, and has to be kept at a VERY tight tolerance. Not too much, or too little.
If the voltage for the Processor is not kept in this tight tolerance range, the Processor turns off. (BIOS turns it off)
How the Electrolytic Paste works inside the capacitor is a chemical reaction.
Capacitor is operating at a weakened state, computer works for a while, then doesn't.
Capacitor/s brake down. (There will be more than one bad capacitor, but all it takes is one. The part of the voltage regulator circuit that handles the Processor, has capacitors in a Series Circuit. Therefore it only takes one bad capacitor)
Then the chemical reaction in the paste takes place again, making the capacitor operate okay for a while. Soon there won't be enough Electrolytic paste left, and the computer won't work at all.
The computer's Power Supply also has Electrolytic Capacitors. (Radial Aluminum design also)
It sounds like an issue coming from the video card..
1.Confirm that the DVI to VGA adapter is connected.
Make sure the adapter is connected firmly to the DVI port on the back of the computer and the VGA cable that is connected to the monitor.
A DVI to VGA adapter is required if the monitor came with a VGA cable and the video card in the computer has a DVI connector.
2.Confirm that the monitor is plugged into the correct video connector.
Check where the video cable is connected on the back of the computer and make sure it is connected to the proper video port.
Some computers that are configured with an add-in video card have an integrated video solution. The integrated video connector is located near the rear I/O connectors such as the printer port, keyboard and mouse connectors. The add-in video card connector is located in an add-in card slot. The integrated video source located near the I/O connectors is automatically disabled if an add-in video card is present.
3.Check the LEDs on the front of the monitor.
The monitor should have an LED on the front bezel or in the power button to indicate that it has power when turned on. When the monitor is in a low power state or has no signal, the LED may be orange or blinking and it may brighten or turn another color such as green when it has established a successful connection to the computer.
If no LEDs can be seen on the monitor when the power button is pressed, check the power cord to ensure that it is properly and firmly connected to the monitor and the AC wall outlet. Plug the power cord directly into an outlet, bypassing any surge suppressors or UPS devices. Make sure the wall outlet has power.
Note: Always reconnect the power cord to a known good surge suppressor when troubleshooting is complete.
4.Look for signal indications on the display panel.
Turn the monitor off and unplug the video cable at the computer or the back of the monitor. Plug the monitor into a known good AC wall outlet, press the power button, and then watch for any messages.
When the monitor is turned on it should display a message indicating that it is functioning normally. The message may be a logo or may prompt "no signal detected". If the monitor does not display a logo or message it could be an indicator that it may not be functioning normally.
5.Use a different video cable.
If a second video cable is available, replace the original video cable with the second cable and retest the computer. Inspect the pins on the original video cable to ensure that none are bent, broken, or pushed inward, preventing a proper connection.
By connecting a new or second video cable that is known to work on a different computer, you can eliminate the possibility of a bad connection or bad cable as the root cause of the issue. If the original video cable does not appear normal upon inspection, connect it to a known good computer to check if it works.
6.If the computer has both integrated video and an add-in video card, remove the add-in video card.
Remove the video card and connect the monitor to the integrated video port. Check to see if the video is now working.
Many later desktop computers have an integrated video solution. If the computer being diagnosed has an add-in video card, check the product page to see if the computer also has an integrated video solution. If it does, remove the add-in video card and connect the monitor to the integrated video connector. Make sure everything is plugged in and turn the monitor and the computer on. If the computer now has video this indicates that the add-in video card is the source of the issue.
7.Confirm that the video card is properly seated.
Unplug the computer from the AC wall outlet and disconnect the video cable from the back of the computer. Remove the cover and locate the video card. Carefully press down on both ends of the video card to ensure it is properly seated.
Pressing down slightly on both ends of the video card ensures that it is completely and properly seated. If the computer is new, the card may have come loose during the shipping process, causing the computer to not display video.
Hi,
Yes all processors on PC motherboards can be replaced.
You just need to find out what processor you are using and then upgrade with the same type but bigger speed..
Thanks
Jason
Unfortunately, this computer does not have support for an expansion graphic card. For your reference please go to this LINK which will take you to the Details and Specifications of your computer. Please let us know if the information has been helpful. Thank you and regards.
Hey thier is some screws holding the case cover to the chassis should be two at least Small phillips head screw's ,and depending on your case it either has a side panel that can be removed by gentally pushing off the side after the screws have been removed ( dont for get to unplug the energy supply cord before seeking to remove the cover) if your comp is a one peice cover you will have o remove at least four screw's to get the cover free to be removed off of the chassis,they also slide back and then come off Hope this helps Steve
There are several options. This is what I would do: Go to the E-Machines site and get the fix from them. If they don't have it I would down load the files to the hard drive and burn a CD. When you make the cd ensure your folders are labeled DISK1, DISK2, ... there should be 1 folder for each disk and then make a folder DSK and put all the files in that folder. As long as none of them share a name you should be good. The cd will need to be Bootable. Boot the machine from the CD and try running the fix from teh DSK folder. If that does not work. Reboot the machine from the cd, Open the Disk1 folder and startt the program. Now, if none of that works or you feel you haven''t really put anything on the computer you need to keep the fastest option to get back up and running is to put the CD that came with the E-machine in the drive and reboot the computer. Choose Repair system or Restore to Factory settings when the menu appears. One of these options will work if your harddrive is not damaged.
Every computer comes built with a processor cooling fan
system.
The fan's main function is to keep the processor from
overheating.
After long periods of use, processor fans can start to
malfunction.
If your eMachines computer's fan is excessively noisy, it
will need some maintenance.
If you don't deal with a noisy fan promptly, your computer's
processor could overheat and cause significant damage to your motherboard as a
result.
WARNING: Before you start troubleshooting remember that you are dealing with
electricity that can KILL.

Some of the below steps
recommend removing physical parts within the computer.
While in the computer it is
highly recommend that you be aware of ESD and its potential hazards.
Power down the computer.
Disconnect all cables and peripheral devices from the
computer's back panel.
Rotate the computer so the back panel is facing you. Lay the
computer on its left side.
Remove the Phillips thumb screws that fasten the right side access panel to the
computer's frame.
Remove the side access panel from the computer to reveal the
motherboard and all internal components.
Locate the cooling fan assembly near the center of the motherboard.
Remove all Phillips screws fastening the fan to the
motherboard.
Disconnect the fan's power cable from the motherboard.
Then lift the fan out of the computer.
This will reveal the processor chip.
Place the fan on a flat work surface with the label sticker
facing upward.
Use a thin, flat-head screwdriver to peel away the label
sticker from the fan.
This will reveal the access hole to the fan motor's
bearings.
Apply one to two drops of lightweight mechanical oil into the fan motor's
bearings.
Replace the fan's label sticker.
Use a can of compressed air to spray the dust and debris from inside the fan
blades.
Place the fan back into the motherboard on top of the
processor chip.
Replace the retention screws and reconnect the fan's power
cable to the motherboard.
Replace the side access panel and its two retention thumb screws.
Place the computer tower vertically, and then reconnect all
cables and devices to the computer.
You will most likely have to remove the HDD from the chassis to access the RAM. Most eMachines utilize either tabs or screws to remove the drive. If you can post some pics of the inside of the chassis I can assist further.
