Your description indicates your power supply may be faulty or there is a break somewhere in the 24 pin main ATX cable wiring.
Swap out the power supply. Make sure your PSU has a 24 pin ATX connector & (not a 20) pin & a 4 pin ATX_12v connector for the CPU.

No Video when the system is turned on


Doesn't quite work that way, and good job on capacitor replacement

!O_O!

What bites is sometimes the Electrolytic Paste dries up, and there is no visual signs of failure.

1) Think I better tell you about the motherboard voltage regulator circuit;

One of the things the motherboard voltage regulator circuit does, is to regulate voltage for the Processor. (CPU)

The Processor MUST have a steady, 'clean', supply of voltage; and it MUST be kept within the tight voltage tolerance range, specified for the Processor.

Cannot be too much, or too little; or BIOS turns it off.

http://www.hardwaresecrets.com/article/616

General thinking would be that the Capacitors that surround the Processor, are the only ones for it.
This is a fallacy.

There could a capacitor, or capacitors; that are in the motherboard voltage regulator circuit, and for the Processor; and are NO where near the Processor.

You actually have to follow the circuit traces, and see.
Example; Is there a capacitor over by the Ram Memory, or another outlying area, that a circuit trace from it leads to the processor socket?

Read the Hardwaresecrets article, and I believe it will help with understanding.

2) Don't know your soldering prowess, not knocking it.
You don't have any cold solder joints, do you?
That will make you pull your hair out, until you find it.

3) The Power Supply thing; the statement that it doesn't work that way;

You could have a Power Supply with a weak voltage power rail.
LED's would light up, and fans may spin; but there isn't enough power to turn the Processor on.

1) If ALL of the LED's were lit up at once, they would use less than 1 Watt of power.

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

3) A typical Processor (CPU) can use 51 to 125 Watts of power.
Just depends on what Processor it is.

When testing; the Processor, processor fan and heatsink, plus ram memory is installed.

You are trying to get the BIOS Setup screen to come up.

Make SURE there is a stick of ram memory in Slot 1. (DIMM 1)
This is the ram memory slot that is closest to the Processor.
The Processor reads Slot 1 first.


Yes. If you have more than 1 ram memory module ('Stick'), trade them around/out, and see if you have a bad ram memory module.

Also suggest clean the gold plated contact pins, on the Ram Memory module; with a pencil eraser.
Use air to remove the eraser dust.

When diagnosing a desktop computer problem, POWER is ALWAYS checked first.
Then see if computer is dirty inside, and then clean ram memory module's, gold plated contact pins with pencil eraser.

If you are not following, or if the person before you was not following; Anti-Static Procedures, use the motherboards for a Frisbee, or expensive paperweight.

Regressing;
There are 3 main voltage power rails;
A) 3.3 Volts
B) 5 Volts
C) 12 Volts
ALL are DC Voltage

In comparison two D cell flashlight batteries produce 3 Volts DC.

A) ALL Orange wires are 3.3 Volts
B) ALL Red wires are 5 Volts
C) ALL Yellow wires are 12 Volts.

ALL Black wires are Ground wires.

Voltage power rail.
ALL Orange wires are 3.3 Volts, and they all end in one central point; inside the power supply; the 3.3 Volt power rail.

Same thing for Red 5 Volt wires, and Yellow 12 Volt wires.

Multimeter red probe lead (Positive) plugged into Red hole on multimeter, that has DCV next to it. DC Voltage.

Function knob set to DC Voltage (DCV)
If just a symbol, the symbol is a dotted line over a solid line.
(Curved line over solid line is ACV. AC Voltage)

If more than one scale, set to 0-50 volt scale, DCV.
0 to 50 volts Direct Current Voltage. (DC Voltage)

Positive (Red) probe lead of multimeter TO power wires.
3.3 Volt (Orange), 5 Volt (Red), 12 Volt (Yellow)

Negative (Black) probe lead of multimeter TO Ground wire.
ALL Black wires are Ground wires.
Read multimeter.
(Power supply on)

You can purchase an economical multimeter, for as little as $5 to $12.
Auto parts stores have them. (A little more pricey usually)
I have seen them on checkout aisle racks, at major discount stores.

No?
Not feasible?
Is there a working computer you can TEMPORARILY, borrow it's Power Supply?
KNOWN to be working, and Compatible Power Supply?
Use for a test unit. See if the Power Supply is the problem.

Not to be a hater, but I would use SuperMicro motherboards; to skip across the lake with.

"Wow! Look at that baby go!"

But DON'T! It's bad on the environment.
(Fish get two heads, and stuff.


NO! Not really. You gonna' believe that? lol!

It IS bad for the environment, however)

Monitor shows no signal when put on. i've checked the graphic card and it seems to have no problem. RAM and CMOS battery are all fine but data refuses to show on monitor. Please i'll need...


A) Power Supply:
Power Supply has a weak voltage power rail.

!O_O!

But the LED's light, and fans spin?

1) If ALL of the LED lights were on at once, they would use less than 1 Watt of power.

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

3) A typical Processor (CPU) can use 51 to 125 Watts of power.
Just depends on what Processor it is.

This is why the simpy little LED's can light, and fans spin; but Not enough power to turn the Processor on.

There are 3 voltage power rails;
A) 3.3 Volt
B) 5 Volt
C) 12 Volt
ALL are DC Voltage.

[In comparison two D cell flashlight batteries produce 3 Volts DC ]

Do you have access to a multimeter to test them with?
Around here an economical multimeter is $5 to $12.
Available at auto parts stores, (A wee more expensive)
I have also seen them on checkout aisle racks, at major discount stores.

I can guide you step by step.

OR,
Do you have a KNOWN to be good, Compatible power supply; that you can use for a temporary test unit?

B) Electrolytic Capacitors:
Specifically - Radial Aluminum Electrolytic Capacitors.

Some motherboards use nothing but those.
Newer motherboards went to using those, plus Solid Polymer Capacitors.
Finally, most new motherboards that are gamer style, use nothing BUT Solid Polymer Capacitors.
(Or whatever the new solid capacitor used is)

C) Next,.........
The front of your computer is the Front Panel.
Disconnect all cables going to the Front Panel, for the USB ports, Firewire ports (1394/1394a), and Card Reader cables.

DO NOT disconnect the cable/wires from the Front Panel header, on the motherboard.

[The area of contact pins on the motherboard, that the Main wires go to, is the Front Panel header.

The main wires are the Power On switch, Power On LED light, HarDDrive activity LED light, and Reset switch, IF used ]

Still no?

Disconnect the Harddrive cable from the motherboard, (Data cable), and the power cable to Harddrive.
Do the same for the optical drive. (CD/DVD drive)

ONLY things to be connected is the;
1) Processor
2) Heatsink
3) Processor Fan
4) Ram Memory

Graphics card, IF it is the only graphics solution.
Otherwise, plug the monitor into the Integrated Graphics of the motherboard.

[Back of computer in the I/O area. The I/O area has a rectangular sheet metal, I/O Shield around it.

Input/Output area.
Input: Mouse, Keyboard, etc.
Output: Monitor, Printer, etc ]

NO cables from motherboard connected to Anything, except Processor Fan, and Front Panel header.

Does the BIOS Setup screen show, when you press the enter BIOS Setup key?

A) PS is NOT fine

B) How do you know the CPU and GPU are fine?

Frigging computer doesn't work, but the Processor, and graphics chipset that is Integrated on the motherboard, is fine huh?
Yeah right.

1) Graphics card being used, or are you using the OnBoard (Integrated) graphics? If so how do you know the GPU is good?

2) What motherboard did you use the Processor (CPU) on to check it out?

3) Same one to check out the graphics card? Where did you download the drivers from?

"If the power light is steady amber, there may be a power problem or an internal device malfunction."

You have a bad Power Supply.
Weak voltage power rail.

Take a multimeter set to DC Voltage, and check the voltage of the 3 main voltage power rails; 3.3 Volts, 5 Volts, and 12 Volts. (All are DC)

An inexpensive multimeter can be purchased for as little as $5 to $12. Available in a multitude of stores. An auto parts store is but one example.

http://en.wikipedia.org/wiki/Computer_power_supply#Wiring_diagrams

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24


A) Orange wires are 3.3 Volts
B) Red wires are 5 Volts
C) Yellow wires are 12 Volts.
All are DC Voltage
D) ALL Black wires are Ground wires.

Positive red ( + ) lead of multimeter touches the power wire.
3.3 Volts (Orange), 5 Volts (Red), or 12 Volts (Yellow)
Negative black ( - ) lead of multimeter touches ANY Black wire.

[In comparison two D cell flashlight batteries store 3 Volts DC.
In case you are worried about getting shocked ]

Looking back at the Playtool link, look at the photo to the far right.
24-pin ATX main power cable is plugged into the motherboard as shown.

Lay the computer on it's side.
A straightened out paperclip is inserted into the Back of the main power cable's connector, and down into the socket hole with an Orange wire in it. (The Back is where the wires go into the connector of the main power cable)

Goes RIGHT NEXT TO the insulation of the Orange wire, and has to go far enough down in the socket hole, to touch a metal terminal at the end of the wire,

http://www.molex.com/molex/products/datasheet.jsp?part=active/0002081202_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US

Another straightened out paperclip, is inserted down into ANY socket hole with a Black wire in it. (I would keep the two paperclips separated pretty far though)

Power supply, (Computer) is plugged into power, and turned on.
Touch the probe leads (Red and Black) of the multimeter, to the two straightened out paperclips.
You should be reading very close to 3.3 Volts (DC)

Do the same test on a Red wire. You are testing for 5 Volts now.
Now the same for a Yellow wire. Testing for 12 Volts.

[All the 3.3 Volt wires (Orange) end in the same central locating point, inside the Power Supply.
Crudely explained that central point, or tap, is the 3.3 Volt power rail.

All the 5 Volt (Red) wires end in one central locating point.
Same for all the 12 Volt (Yellow) wires.
Hence 3.3 Volt power rail, 5 Volt power rail, 12 Volt power rail ]

Light Emitting Diodes may light up, fans may spin, but there is not enough power to turn the Processor on.

1) If ALL of the LED's were on at once mdrod, they would use less than 1 Watt of power.

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

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

Pls help my computer shows no display


CPU fan runs, harddrive picks up, but no display.

1) Bad Power Supply
Or
2) Bad graphics chipset.

The two main factors for desktop computer failure, is a bad power supply, and/or the computer is dirty inside.

A) Bad Power Supply

Weak voltage power rail
Enough power to light LED lights, and perhaps spin fans, but not enough power to turn the Processor on.

IF all of the LED lights were on at once, they would use less than 1 Watt of power.

EACH fan uses 2 to 3 Watts

A typical Processor can use from 51 to 125 Watts.
Just depends on what Processor it is, as to what the maximum Wattage usage is.

CPU fan runs? Sure. It's only using 2 to 3 Watts.

Harddrive 'picks up'? You will hear the Spindle Motor spinning the Platters inside. Means nothing.

With no Processor running, BIOS can not hand the computer over to the Operating System. (WinXP is one example of an O/S)

There is nothing to find the Boot Record, on one of those Platters inside the harddrive.

(Explanation of physical construction of an average Harddrive,

http://computer.howstuffworks.com/hard-disk.htm )

You can check the Power Supply voltages out. See if there is a weak voltage power rail.

Power coming into the Power Supply is the dangerous voltage.
Power coming out of the Power Supply is not.

The Power Supply in your Personal Computer is an SMPS.
Switched-Mode Power Supply,

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

Your Power Supply converts the electricity from your home, or business, into three main voltages,

A) 3.3 Volts
B) 5 Volts
C) 12 Volts

All are DC voltage. (The incoming electricity from your home or business, is AC voltage)
{In comparison two D cell flashlight batteries produce 3 Volts DC}

Use a multimeter to test the voltages. If you do not have access to one, an economical multimeter can be purchased for around $8 to $12. A multitude of stores carry them. An auto parts store is but one example.
Analog or digital, it doesn't matter. (I prefer Analog)

Set the Function Knob to DC voltage. (If just a symbol is used it is a dotted line over a solid line)

If there is more than one setting for DC Voltage, set it to the 0 to 50 Volts scale. (0-50)

The red probe lead is the Positive lead.
The black probe lead is the Negative lead.

The Positive probe lead touches the power wire
The Negative probe lead touches a Ground wire.

The 3.3 Volt power rail, the 5 Volt power rail, and the 12 Volt power rail, are the power wires.
Test one at a time.

ALL Black wires are GROUND wires.

Test at the ATX main power cable's connector.
The ATX main power cable is plugged into the motherboard. The Power Supply is plugged into power.

The ATX main power cable used for a Gigabyte GA-K8VM800M motherboard,
is a 20-pin ATX main power cable. This is an example of a 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

Note the photo to the far right. The ATX main power cable is plugged into the motherboard.
Testing the voltages is done at the Back of the connector. Back of the ATX main power cable connector. The Back of the connector is where the wires go in.

The probe leads tips, will not fit down into the socket holes, next to the wires already present.
Suggest use an adapter. Suggested adapter is a paper clip.

The paper clip is straightened out, then inserted down into the socket hole, RIGHT NEXT TO THE WIRE that is already there.
The paper clip Must go down into the socket hole, to touch a metal terminal.

At the end of every wire going into the ATX main power cable connector, is a metal terminal. You have to go down past the insulation of the wire, and touch the metal terminal with the paper clip.

A) The Orange insulated wires are 3.3 Volts
B) The Red wires are 5 Volts
C) The Yellow wires are 12 Volts.

Example to test a 3.3 Volt power rail;

Power Supply unplugged from power insert a straightened out paper clip into a socket hole with an Orange wire. Leave it sticking up.

Now insert a straightened out paper clip, into ANY socket hole with a Black wire. (Ground)

Plug the Power Supply into power. Touch the red Positive probe lead of the multimeter, to the paper clip for the Orange wire. Hold it there.
Now touch the black Negative probe lead to the paper clip for the Ground wire.
(Black wire)

You should read VERY close to 3.3 Volts.

Same procedure for the 5 Volt power rail, and the 12 Volt power rail.

{Power Rail;
All 3.3 Volt (Orange wires), end at one central point in the Power Supply.
This central point is the 3.3 Volt power rail.
Same for the 5 Volt, and 12 Volt wires.

You can test any wire of that voltage, and be testing the entire power rail, for that voltage }

Power Supply checks out?
Graphics chipset.

Chp and Chipset are slang terms for I.C.
Integrated Circuit,

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

The graphics chipset is a GPU.
Graphics Processing Unit,

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

A GPU can be soldered directly to the motherboard, or to a removable card.

Soldered directly to the motherboard is Integrated Graphics.
Also known as OnBoard graphics. (ON the motherBOARD)

Soldered to a removable card is a Graphics Card.
(Full name is Graphics Adapter Card)

If you are using Integrated Graphics, try using a graphics card.
If the graphics card works, the problem is bad Integrated Graphics on the motherboard.
The graphics card bypasses using Integrated Graphics.

{The above is that you are seeing No Signal on the monitor.
If not check the monitor, AND the monitor cable to see if they are good. Test on a known to be good, working computer }

A bad Power Supply with a weak voltage rail, will produce the symptoms you've just described.

1) IF all of the LED lights were on at once, they would use less than 1 Watt of power.

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

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

You press the Power On button. The first chipset (Integrated Circuit) to receive power is the BIOS chipset.
BIOS detects what devices are installed, does a Ram Memory count, turns the Processor on, and hands the computer over to the Operating System.
(Windows XP is one example of an O/S)

Have you tested the main voltages of the Power Supply?
A) The 3.3 Volt power rail
B) The 5 Volt power rail
C) The 12 Volt power rail

(12 volt rail must be 11 volts or more. Less = new Power Supply)

Blank screen on start up


Try removing all cards with the exception of the video. Remove all memory leaving (1) to boot from.
Disconnect power and reset the processor.
If you have a boot disk or copy of XP on disk, try to boot from the CD or DVD.
If the unit boots at all the problem may be the HD.
If not try downloading the BIOS update for your chipset.
Remove all extra drive, like secondary CD or DVD drives, Floppy or Zip drives.
You may have burnt the processor but I don’t think so.
Power supply is OK or you would not power up. Their are 3 or 4 supply voltages from supply, +- 12 volts, +- 5 volts and +-3.3 volts.
You may have a secondary 12 volt 4-pin plug but that is for on board video.
Try a boot disk and flash your BIOS, if you can.
Hope this helps.

Board power is ok but run cpu&fan plz give me answer


1.Check the Electrolytic Capacitors on the motherboard. Specifically the one's around the processor. These are Voltage Regulators for the processor.
The processor must have DC voltage within a specific range. This zone, or range is very small. Too much voltage, the processor turns off, or won't start up. Too little voltage does the same.

This link will show what Electrolytic Capacitors look like, and what they look like when they are failing, or have failed,

Electrolytic Capacitors are the number one weakest link, of computer hardware failure.
For ease of explanation of construction of them, they look like little aluminum pop cans, they have a rubber seal at the bottom of them, and inside them they have Electrolytic paste.

When the capacitors start to fail, the paste inside develops a gas.
(Hydrogen gas) This gas expands, and pushes the against the seal. The seal's edge pushes out of the 'can', and paste starts to ooze out. So much paste loss, and the capacitor operates at a weakened state. Too much paste loss, and the capacitor fails.

Besides the motherboard capacitors failing, the next area to watch are the one's in the power supply. Power supply's have voltage rails inside. More specifically, they have a 3.3 volt rail, a 5 volt rail, and a 12 volt rail. Voltage may be thought of as the 'speed' of electricity. Amperage may be thought of as how much.
Volts times Amps = Watts.

If you have a power supply with weak, or failed capacitors, you won't be getting the full wattage your computer needs. Your motherboard power light will light up, other lights will light up, fans will spin, and the harddrive sounds like it's working.

ALL the lights use less than 1 Watt.
EACH fan uses 2 to 3 Watts.
The harddrive just sitting there spinning it's platters, uses about 3 to 5 Watts.
PROCESSORS use 55 to 125 Watts!!

So you see you can have lights lit, fans spinning, and the harddrive spinning, but when BIOS tries to turn the processor on, it can't!
Not Enough POWER!
