Emachine 5210 not working

Several things xopunkyxox.

No Signal means there is no Video Signal coming from the computer. The monitor is working fine.

eMachines computers are budget computers. This means they sell for a low price, but also have low quality hardware components used inside the computer.

There are two top issues for computer failure. These really affect an eMachines computer.

1) Power Supply
The PSU (Power Supply Unit) used is a low quality unit to begin with, in an eMachines.

2) Dirty computer.
Dirt, dust, etc., can bring a computer down to it's knees.

The eMachines W3118 desktop computer uses an FIC K8MC51G motherboard.
(First International Computers, inc)

(The eMachines W3118 desktop computer is a North American model)

FIC K8MC51G Specifications:

http://support.gateway.com/s/MOTHERBD/FIC/105554/105554sp25.shtml

http://www.fic.com.tw/product/motherboard/AMD/K8MC51G.aspx

The eMachines W3118 motherboard has a Socket 754 processor socket.
Comes with an AMD Sempron 3100+ processor.
(1.8GHz)

AMD processors run HOT. Keep the Heatsink, and Fan on top of the processor, CLEAN.
The Thermal Compound (Thermal Paste or Thermal Grease) that is in-between the top of the Processor's case, and the bottom of the Heatsink, can dry out over time.
The heat developed by the Processor when operating does this.

A Power Supply (SMPS) has two cooling features.
1) The internal fan that you can see by looking at the back of the Power Supply, (Back of computer)
2) Heatsinks used inside the Power Supply.

Example of an internal view of an average SMPS,

http://en.wikipedia.org/wiki/Switched-mode_power_supply

Click on the photo to the top right. In-between the letters B and C, and also C and D, are aluminum Heatsinks.
What looks to be finned rectangles arranged in a vertical strip.

When the fan's blades, center hub, and surrounding cage, (Shroud) are clogged with 'gunk', the cooling capacity of the Fan drops tremendously.

Same thing with the fins of the Heatsinks.

[Construction of an average Heatsink is a plate of metal with tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object it is placed against, and the tall, thin fins absorb heat from the plate of metal.

The fins then radiate the heat away. With a fan used in conjunction with a Heatsink, the fan pushes air in-between the fins, and around the fins. The air flow helps carry heat away]

Heat = Wasted Energy
The overheated Power Supply strains to keep up with the call for power, but eventually fails.
(Hardware components inside the Power Supply fail)

I'm willing to bet it's Power Supply failure.
Test the three main voltages from the Power Supply. (3.3 Volts, {Orange}, 5 Volts {Red}, and 12 Volts, {Yellow)

The next thing to be an inherent problem with an eMachine desktop computer, are the Electrolytic Capacitors on the motherboard.
Low quality capacitors are used.
(Radial Aluminum Electrolytic Capacitor)

Visual identification of bad capacitors, (Electrolytic),

http://www.capacitorlab.com/visible-failures/index.htm

[NOTE*
Not all bad Electrolytic Capacitors show visual signs of failure. Sometimes the Electrolytic Paste inside the capacitor dries up. No bulging case, or leakage will be present ]

Summary:
1) Computer unplugged from power, Anti-Static Precautions observed, clean the inside of the computer out.
2) Replace the Power Supply.

Also remove the Ram Memory modules, ('Stick'), and clean the gold plated contact pins on the ram memory module, with a pencil eraser.

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

(You can click on the photo to enlarge)

Your eMachines W3110 uses DDR Sdram ram memory.
184 contact pins. 92 on Each side.

[It is DDR Sdram that operates at either 333MegaHertz {333MHz}, or 400MegaHertz. {400MHz}. Also know as PC2700 or PC3200, respectively]

Handle the ram memory by the body. Refrain from touching the contact pins.
The body of the ram memory is coated with a see-through protective plastic, which shields it from Static.

The pencil eraser is rubbed going Down the contact pin. Start at the top, and go down. If you are using the eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band touch the contact pins.

After you have cleaned each contact pin it may look as though you have not done very much.
I assure you have. Doesn't take much 'corrosion' on a gold plated surface.

Use air to remove the eraser dust before reinstalling the ram memory.
You can use a can of compressed air for computers, or air pressure from your mouth will be sufficient.

Use compressed air to clean out the ram memory slot/s on the motherboard also.

The smell is the Power Supply.

Typical example of a Power Supply not installed in a desktop computer,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4435072&CatId=106

[ NOTE*
This is not an example of a direct replacement Power Supply for your computer. I would need to know the Model Number of your eMachines to give exact information ]

Bad Power Supply. Weak voltage power rail. (Or rails. There are three main voltage power rails for a Power Supply used in an eMachines desktop computer)

Enough power to light LED lights, and apparently spin fans, but Not enough to turn the Processor on.

Watts = Voltage times Amperage.
One measurement used for measuring the maximum available power output, of a desktop Power Supply, (SMPS. Switched-Mode Power Supply), is to state the Maximum Wattage available.

Typical maximum Wattage available for a typical eMachines Power Supply, usually averages from 150 to 300Watts.

1) ALL of the LED lights on at one time, will use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power.
Depends on what Processor it is.

(Note* Intel Pentium II processors use less than 51 Watts)

Solution is to replace the Power Supply.
This isn't as hard as it 'sounds', if you have never performed this procedure before.
I know you can do it.

If you need guidance in replacing the Power Supply in a step by step for your eMachines, please post in a Comment. (Believe upper right of your page)

Should you also desire recommendations to compare for a Power Supply, I would be happy to provide them.

LED lights are on? Fans spin? I suggest you have a bad Power Supply.

1) eMachines are noted to have low quality Power Supply's.
Saves eMachines money so they can sell budget computers.

2) A bad Power Supply is one of the leading causes of computer failure. I have, (Had actually), a shop half full of computers with this 'ailment'.

Some caused by the owners never cleaned out the inside of their computer, nor the inside of the Power Supply, with a can of compressed air for computers on a regular basis as needed.

3 to 5 years without cleaning the inside of their computer.
Mice could have made nests inside easily, with the 'Gunk' that was there. A bald eagle could have too. Rant off.

Others, caused by the computer manufacturer used a low quality Power Supply.
Low quality components used inside.
One of the major components that fails, is caused by a particular Electrolytic Capacitor that is used.

http://en.wikipedia.org/wiki/Capacitor_plague

3) Power Supply's used in PC's are a type of SMPS.
(Personal Computer. Statement holds true no matter what type of personal computer it is)

[ SMPS = Switched-Mode Power Supply
PSU = Power Supply Unit
All terms relate to a Power Supply used in a PC ]

A bad Power Supply will have a weak voltage power rail.
There are three major power rails used in the ATX form factor Power Supply, for an eMachines T6420 desktop computer.

A) The 3.3 Volt power rail (DC)
B) The 5 Volt power rail (DC)
C) The 12 Volt power rail (DC)

(Two D cell flashlight batteries produce 3 Volts DC)

A Power Supply with a weak voltage power rail, may have enough power to light LED lights, and spin fans, (or spin a few times, ans stop), but won't have enough power to turn the Processor on.

1) ALL the LED lights combined use less than 1 Watt of power

2) EACH fan uses 2 to 3 Watts

3) A typical Processor can use 51 to 125 Watts.
Depends on what Processor it is.

eMachines T6420?
Uses an AMD Athlon 64 3400+, processor.
(Socket 939)

[The motherboard used is an MSI ms-7207
Also known as K8NGM2-L ]

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T%20Series&model=T6420

This Processor can use Up To 89 Watts.

http://en.wikipedia.org/wiki/List_of_amd_athlon_64_processors#.22Newcastle.22_.28CG.2C_130_nm.29

No Processor running, No computer.
No computer = No Video Signal

Suggest using a KNOWN to be Good, Compatible power supply, for a test unit, if available.

Should be the ATX form factor.

Approximately 6 inches Long, (15.24cm), 6 inches Wide, (15.24cm), and 3-1/2 inches Tall. (8.89cm)

250 Watts.
Correct amount of power cables, and the correct type.

If the keyboard doesn't briefly light up the Caps Lock, and Numlock keys, when first starting the computer, and there's no video signal to the monitor, (No Signal), the computer isn't working.

Suspect the Power Supply first.

Bad Power Supply, is one of the most leading causes of computer failure.

This is brought about usually by one of two things, or a combination of both.

1) eMachines are Budget line of computers. Cheap quality parts are used, to defray the cost of making the computer.
One of the cheap hardware components is the Power Supply.

2) Computer is dirty inside, as well as the Power Supply.
The hardware components inside a computer, as well as the Power Supply, are cooled by air from fans.

Dirt, dust, etc, cause the cooling capacity of the cooling system, to drop tremendously.
Heat = Wasted Energy.

The Power Supply tries to keep up with the call for power, cannot, and components inside the Power Supply fail.

The Power Supply has a weak voltage power rail.
It may seem that the computer is receiving power, but it isn't receiving enough.

A) ALL the lights use less than 1 Watt of power

B) EACH fan uses 2 to 3 Watts of power

C) A typical Processor uses anywhere from 51 watts to 125 Watts.
Depends on what Processor it is.

The W3506 comes with an Intel Celeron D 352
(Single core processor, that operates at a maximum frequency rate of 3.20GigaHertz. 3.2GHz)

eMachines Support>Specifications>W3506,

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=W%20Series&model=W3506

Information on the Intel Celeron D 352 processor,

http://en.wikipedia.org/wiki/List_of_Intel_Celeron_microprocessors#.22Cedar_Mill-512.22_.2865_nm.29

The Intel Celeron D 352 can use up to 86 Watts, when operating at maximum capability.

This is why it may seem as though the computer is working, but in actuality it isn't.
The Processor isn't running.

No Processor operating, no computer.
No computer, No Signal to the monitor.
No Processor running, there is nothing to make the Operating System work. (Windows XP is one example of an O/S)

No Operating System working, the keyboard isn't going to 'light up'.

From here the diagnoses should be to test the Power Supply, or replace it with a KNOWN to be good, compatible power supply for a test.

[Compatible being the Power Supply has enough Wattage, the correct power cables, and enough of the correct power cables]

The Power Supply can be tested in the computer, with all the power cables disconnected.
Use a multimeter, or a power supply tester.

Example of an economical Power Supply Tester,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5250576&CatId=5471

This gives information on the various power cables used, in a personal computer,

http://www.playtool.com/pages/psuconnectors/connectors.html

Using the multimeter, the Positive (Red) probe is connected to the power wire to be tested, then the Negative (Black) probe is touched to a Ground wire.

There are three main voltages, given out by a personal computer power supply, (All are DC volts),

1) The 3.3 Volt power rail.
Wires that have Orange insulation are 3.3 Volt wires

2) 5 Volt power rail. Red insulated wires
3) 12 Volt power rail. Yellow insulated wires

For 12 Volt power, 11 to 13 Volts is okay. Below 11 Volts it's time for a new power supply.

4) ANY Black wire is a Ground wire.

Questions? Post in a Comment.

look on bios to see if detects the hard drive ...if does not boot to windows...the hard disk has no reason to go on ....and the issues could be many ....check the Ram memory if do not appear anything on screen at all ...and just runs the coolers and clicks without boot at all...in this case its the Ram memory ...so check it ...get it out ..put it back ...and remove the bios battery to force it see them again .....if it is booting until the operating system should appear ...and after that nothing ...reinstall ...
Also .....if there is anything written on the screen ..read carefully ..usually it will say whats wrong ...and advise in same issues..like replace hdd ...or files missing ...or blue screen error from memory issues..

The power supply is bad. Electrolytic Capacitors inside the power supply. The 'Caps' are filters for the power supply. (Used in both the Input Stage, and Output Stage)

Inside the power supply are Voltage Rails. The 3.3 volt rail, the 5 volt rail, and the 12 volt rail.
Bad capacitors = a bad voltage rail. Not enough power from the power supply. Your processor doesn't have enough power to turn on, or stay on.

Why is the fan running?
ALL the lights use less than 1 Watt of power.
EACH fan uses 2 to 3 Watts.
A processor can use 55 to 125 Watts. Depends on what processor it is.
Plenty of power to spin a simple fan, but not enough power for the processor.

Yes I'm sure, is the answer to your question.
(No I'm not psychic. Approximately 80 percent of the computers that come into my shop, have bad power supply's)

Do you mean the power supply fan or the processor fan? Of the assemblies in a desktop, the power supply is the least reliable and the internal fan the most unreliable part. Since a failed fan can allow other parts of the supply to degrade, I recommend replacing the supply, not just the fan.
In eMachines, these are standard form factor (ATX) supplies so you would only need to order the same or higher power rating to have it compatible with your case.

remove the processor,ram for 30min and put them back

Emachines used to use a poor quality power supply made by Bestec, I believe the quality is supposed to have improved in the last few years but inconsidering the number of dead Emachines that wind up in my workshop I doubt it.
The problem you have is that being a poor quality power supply there is a very high risk that it damaged the motherboard when it went out.
If you can borrow a power supply just to test with all the beter BUT be carefull some Emachines are proprietary and the main motherboard plug is not always wired in the standard way.
Check here for a replacement power supply if you can prove your motherboard to be OK.

Have a look on this site for examples of standard and proprietary power supply wiring colours.

Can you hear fan inside the PC? Any flashing lights next to the power button? Please give us more details.
