1. for what you describe could be the sound card cable from the DVD or CD ROM
not sure without a physical look at the cable. there should be a black connector either at the
top corner of the mother board or by the pci slots that the connector is placed.
If you have a sound card mounted in a PCI slot then there is a connector on that board
for this cable.
I hope this helps. Have great day!

Desktop shut down in few seconds after getting display


Good day,
The problem you describe is probably due to a faulty power supply.
The four pin connector which you unplugged supplies power to the CPU, which means you will not be able to get a display with it plugged out, as there will be no power to your CPU.
The fact that the PC does not shut down when removing the 4 pin connector strengthens the evidence that your power supply is faulty. By removing the 4 pin connector you are reducing the power required from the power supply to the point where it is not 'overloaded' enough to switch off.
You can test this by plugging in the 4 pin CPU power connector, then unplugging something else, such as the DVD writer.
Then switch on your PC and see if it still shuts down.
If it remains on then the cause of your problem is definitely the power supply.
Replace the power supply and make sure it has a wattage rating of 400 watts or more. These power supplies are relatively cheap, and should be available at your local PC store for about $15.
Best wishes,
Graeme.

I replaced my power supply and don't remember where the connections went


Not too much way you can go wrong. There's a 20 or 24-pin connector which plugs into the motherboard in only one place. There probably is a 4-pin connector and that, too, goes into the motherboard (in a socket near the CPU). The other connectors are power connectors for you hard drive and CD/DVD. That's about it.

Recently changed the power supply. There is no video output. Where can I download the motherboard schematic?


Right here at HP Support,

1) Motherboard Specifications:

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00361570&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=459491

Scroll the page down to the top view illustration, and photo.

A) The motherboard uses a 24-pin ATX main power cable.
In the illustration the connector on the motherboard is on the right side.
It is an empty rectangular box with ATX Power Connector in it.

On the motherboard photo it is the rectangular white connector with two rows of 10 socket holes, and is to the bottom right of ram memory slot 2.

Another example of a 24-pin ATX main power cable,

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

Ensure that the 24-pin ATX main power cable's connector, is locked into place on the motherboard's connector. The lock tab on the main power cable must be hooked over the tab on the motherboard connector. This ensures that the main power cable is in all the way.

B) The motherboard uses a 4-pin ATX +12 Volt power cable.
The connector on the motherboard is a white square connector, with 4 socket holes.

In the illustration it is to the bottom left corner of the Processor socket (LGA 775), and has ATX12V underneath it. This power cable's connector also has a lock tab.
Another example of a 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Power TO the motherboard, that's it.

Power FROM the motherboard:

C) System Fan, and CPU (Processor) Fan.

Abbreviated as SYS_FAN, and CPU_FAN to the bottom left of the ATX12V connector.
(4-pin ATX +12 Volt connector on the motherboard)

The System Fan is the computer case fan.
CPU Fan is the Processor fan.

D) The four SATA headers on the bottom right in the photo, (Blue, Orange, Black, and White), are for the SATA data cables.
They connect to a SATA harddrive, or SATA optical drive. (CD/DVD drive)
(They are an L shaped connector inside, with 7 pins inside)

Power for these SATA devices comes from the Power Supply.
The Power Supply has SATA power cables.
Example of an average SATA power cable,

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

(L shaped connector with 15 pins inside. The longer connector between a SATA data cable, and a SATA power cable )

Did you forget which SATA data cable plugs into where, on the motherboard?
Don't sweat it.

The beauty of SATA is that you can plug the harddrive's SATA data cable into ANY of the SATA headers (Connectors) on the motherboard, and BIOS will find it.
Same with a SATA optical drive, or any SATA device, for that matter.

IF, your SATA harddrive has a place on the back for BOTH, a SATA power cable, and a 4-pin standard Peripheral power cable, ONLY use the SATA power cable.

Using both will eventually burn out the SATA harddrive!

Example of a 4-pin standard Peripheral power cable, (Misnomered as 'Molex'),

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

From there the main optical drive, (CD/DVD drive), has to have the audio cable plugged into the audio connector on the motherboard.
(Plus the power cable, and data cable, of course)

In the illustration this is the header down in the very far left corner, and located towards the bottom edge.
It has CD_IN marked underneath it.

In the photo it is the Black rectangular connector in the very far left corner.

If you didn't connect the 4-pin +12 Volt power cable, your Processor isn't getting any power.
No Processor operating, No computer.

No Signal on monitor.
(No video signal)

We took our case apart to clean the fans. unfortunately once we had them clean and put back on the on-off switch would not come on it will not power up, the fan is going the green light on the back is on.....


1) Remove the Ram Memory module/s, and reinstall them.

It may look as though they are seated, by they may not be. All it takes is a slight bump.

I would also advise cleaning the contact pins while the ram memory module/s are out.
Use a pencil eraser.

{Note*
Computer unplugged from power, observe Anti-Static Precautions.

Anti-Static Precautions:

Your body carries Static electricity.
Static WILL fry out (Short Circuit) the hardware components inside a computer.
You won't see it or feel it.

Relieve your body of Static Before you reach inside your computer. (And before you remove any new hardware parts from their protective anti-static cartons)
Computer on a table, computer unplugged from power, computer case open.
TOUCH the metal frame of the open computer case to relieve your body of Static.

Should you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.


If you are not using a solid eraser, and one on the end of a pencil, refrain from letting the metal band touch the contact pins.

The Presario SR1403wm desktop computer supports DDR Sdram ram memory modules.
There are 184 contact pins. 92 on each side.

Rub the eraser up, and down on each contact pin, both sides of the ram memory module.
Doesn't take as long as it sounds.
Just go up, and down a couple of times, you don't need to scrub the contacts with the eraser.

It may look as though you have done nothing at all once you're finished. The gold plated contact pins will not be shiny.
I assure you that you have.
Doesn't take much corrosion to make a bad contact surface.

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

(You can click on the photo to enlarge)



2) Perhaps one of the power cables wasn't attached to the motherboard.
Here is an illustration and photo of the Presario Sr1403wm motherboard,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00257657&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&site=null&lang=en&key=null&product=501310

Scroll down towards the bottom of the page.

In the illustration where it states the chipset SiS 760 in a rectangular outline, look to the right of it.
There is a small square outline with > ATX12V1 above it.

This is for the 4-pin ATX +12 Volt power cable.

Example of a typical 4-pin ATX +12 Volt power cable, and the matching connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Be sure this power cable has been attached.

To the right of the motherboard connector ATX12V1 is the main power cable connector
ATXPWR1

On the motherboard photo look all the way to the right side, and in the middle.
The whitish connector that has 2 columns of 10 socket holes is the ATXPWR1 connector.

This is an example of a typical 20-pin ATX main power cable, and it's matching connector on the motherboard,

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

Both connectors have a Lock on the side of the male connector. The connector that has the wires in it.
The female connector on the motherboard has a tab on the side.

To ensure that the male connector is seated tightly into the motherboard connector, the Lock's hooked end must be over the tab on the motherboard connector.

If both of these power cables are not fully seated, the computer will not turn on.



3) Harddrive power cable:

The harddrive used is a SATA harddrive.

This is an example of a typical SATA power cable,

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

Make sure this power cable is seated well, into the SATA harddrive.

[ Note*
The SATA power cable has 15 pins. The SATA data cable has 7 pins.

IF, your SATA harddrive has a provision for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY USE the SATA power cable.
Using both power cables will burn up the SATA harddrive.

Some SATA drives will operate for a while with both cables plugged in. Then they eventually burn up.

Example of a typical 4-pin standard Peripheral power cable,

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

(Shown plugged into an IDE {PATA} harddrive)

With all power cables attached, and seated well, plus the ram memory module/s, make sure the Front Panel cable is connected in the proper place on the Front Panel header.

In the illustration F_Panel 1 is the Front Panel header.

{The plastic front of your computer is the Front Panel.
The area of pins in the connector on the motherboard, that the Front Panel cable connects to, is the Front Panel header.
This particular Front Panel cable is for the Power On switch, HarDDrive Activity LED light, and Power On LED
Not the cables for the USB ports, or Firewire port/s in the Front Panel)

If everything checks out above, then either the Power On switch is bad, or the Power Supply is bad.
Happens. A power supply can go out all at once.
Weak voltage power rail.

I can guide you with a simple test to see if the problem is the Power On switch, or the Power Supply.


If you have further questions please post in a Comment.
Would appreciate hearing how this comes out.

When I turn it on monitor reads vga no input and the power is on, the fan is still running.


Bad Power Supply. Weak voltage power rail.

Has enough power to light LED lights, and maybe spin fans, but not enough to turn the Processor on.

1) ALL of the LED lights on at once use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

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

The Compaq Presario SR2013WM desktop computer, comes with an AMD Athlon 64 3800+ processor, that fits in a Socket AM2.

1) http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00777760&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=3300335


Can use up to 62 Watts.

2) http://en.wikipedia.org/wiki/List_of_AMD_Athlon_64_microprocessors#.22Orleans.22_.28F2_.26_F3.2C_90_nm.29

No Processor operating, no computer.
No computer operating, No Signal to the monitor. (No video signal, or also known as No VGA Signal)

The Power Supply used is just one of the common ATX form factor power supply's.
Used in over 80 percent of PC's out there, and readily available.
(ATX size of the power supply case, is approximately 5-1/2 inches Long, 3-1/2 inches Tall, and 6 inches Wide)

It is 250 Watt, and a generic model. Probably made by Bestec, Delta, or HiPro.
(You can use a larger wattage Power Supply with NO problems.
A computer ONLY uses the power it needs, and NO more)

A) The ATX main power cable is a 24-pin ATX main power cable. All of the new power supply's have an ATX main power cable, where the connector can be used as a 20-pin, or 24-pin.

B) Uses a 4-pin ATX +12 Volt power cable.

C) Past the two power cables above, just make sure the Power Supply has a SATA power cable, (For the SATA harddrive), a Floppy Drive power cable, (Used for the Card Reader), and enough 4-pin standard Peripheral power cables.
(Misnomered as 'Molex')


3) Typical 24-pin ATX main power cable,

4) Typical 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

5) Typical SATA power cable,

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

IF, the SATA harddrive has a provision for using a 4-pin standard Peripheral power cable, AND a SATA power cable, ONLY USE THE SATA POWER CABLE.

If you use both you will burn up the SATA harddrive.


6) Typical 4-pin standard Peripheral power cable,

My computer just stoped working. It wont power on and when I hold the power button there is just a blue flashing light


Bad Power Supply.
Weak Voltage power rail.

The Pavilion a6000n desktop computer uses an ATX style of power supply, and is rated at 300 Watts.
(Probably made by Delta Electronics)

The ATX style of Power Supply is used in over 85 percent of PC's. Very common unit.

[Case size is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall ]

What you are looking for is an ATX power supply with at Least 300 Watts, and the correct power cables.

Note that a computer only uses the power it needs, and No more.

Wouldn't matter if you had a 10,000 Watt Power Supply, (Exaggeration), and the computer only needed 100 Watts, it will only use 100 Watts.

(Surfing the internet typically uses 100 Watts.
Computer. Monitor uses it's own power, and is separate from this figure)

This is HP Support > Pavilion a6000n desktop computer > Specifications,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00873231&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&product=3377269&lang=en

1) Scrolling down the page, and looking at the photo of the motherboard, you can tell the Power Supply must have a 24-pin ATX main power cable.

To the right of the Blue, and Black ram memory slots is the 24-pin ATX main power cable connector, on the motherboard.

It is White in color, and consists of 2 rows of 12 socket holes.
24 total.

On the illustration it is marked as - ATXPOWER.

This is a closer look at a typical 24-pin ATX main power cable, and it's respective connector,

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

Note the Lock on the side of the connector. The Lock is hinged in the middle, (Plastic), and operates like a see-saw on a playground.

Squeeze the top of the Lock in to remove the 24-pin ATX main power cable.
ONLY gently pull up on the connector, and NOT the wires.

[This action brings the hooked end of the Lock away from a 'Bump', or protrusion, that is present on the female connector, on the motherboard ]

2) The Power Supply must also have a 4-pin ATX +12 Volt power cable.

On the illustration where it states Socket AM2 is the Processor socket.

To the left, and down a little of the Processor socket, is a blank square.
The writing under it is illegible.

This is where the 4-pin ATX +12 Volt power cable plugs in.

On the motherboard photo it is to the left of the white Processor socket, and is square in shape, with four socket holes.

This is a better look at a 4-pin ATX +12 Volt power cable, and it's respective connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Color of the plastic used in the connectors, does not matter.

3) Looking at the Specifications page, you will see that the Power Supply must have at least 1 SATA power cable.
It's used for the 250GB SATA harddrive.

Closer look at a SATA power cable, and it's respective connector,

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

NOTE*
If the SATA harddrive in your computer has a place for a SATA power cable, and a 4-pin Peripheral power cable, ONLY use the SATA power cable.
DO NOT use both.

4) Again looking at the Specifications page, the Power Supply must have at least two, 4-pin Peripheral power cables.
Used for the optical drives.
(DVD drives)

A closer look at a 4-pin Peripheral power cable, and it's respective connector,

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

There may be more 4-pin Peripheral power cables needed, to run any computer case fans.

How do I replace a power supply on a Compaq Presario SR5110NX Desktop PC


you can purchase a power supply from any computer store *********** board supports both standard IDE and Serial ATA connections, so you want a power supply that does SATA power as well. Unplug the power cord from the back of the computer. remove the cover from the case and verify that there is no green LED on the board that is lit up (if there is, there is still power on the board). unplug all connections from the current power supply, including all drive power and the large 24pin plug (actually a 4 pin plug that is combined with a 20 pin plug) on the board, then unplug the 4 pin plug near the processor. careful that the 24 pin plug and the additional 4 pin plug near the processor have latches on the side. Remove the 4 screws that hold the power supply in and remove the power supply, install new supply and reinstall the 4 screws. first plug in the 4 pin plug that connects with the 20 pin, the 4 pin plug has no latch, it is held in place by the 20 pin plug. then plug in the 20 pin plug and the 4 pin next to the processor. then plug in the drive power to all of the drives. Install the power plug at the back of the system and you should see a green LED on the board when you insert the power. replace the cover and power the system up.

My dc7100 has a compact power supply with proprietary 24 pin plug. Pretty sure power supply is non-functional (shorted green to black and fan didn't come on). Is it possible to rewire a conventional ATX...


I just spotted this, hence the late solution. Perhaps this will help someone in the future.

Yes it is possible.

Observe the color code of the insulation of the wires.

1) Orange wires are 3.3 Volts

2) Red wires are 5 Volts

3) Yellow wires are 12 Volts

4) The Green wire is the Soft Power On wire

5) All Black wires are Ground wires. Doesn't matter which Black wire it is, it's a Ground wire.
(It isn't a Common wire. This is DC electricity, not AC)

These are your main voltages, and wires to be concerned with.

Fortunately all HP, (Or any proprietary computer manufacturer in that time period), did, was to change where the wires are placed in the 20, or 24-pin ATX main power cable connector.

They just moved the wires in the socket holes, didn't change the color code.

Solution is,
1) To remove the wires in the ATX power supply, main power cable connector
2) To remove the wires in the proprietary computer's ATX main power cable connector.

(NOTE*
BE SURE to make a concise, clear, drawing FIRST, of where the colors of the wires went in the proprietary connector, BEFORE you remove them!)

3) To reinstall the wires into the proprietary connector.
(Again. Following the color code of the wires you removed)

Removing the wires out of the 20, or 24-pin ATX main power cable connector:

Observe these photos, of a 20-pin ATX main power cable's connector. This procedure can be applied to a 24-pin ATX main power cable connector also. (Or a 20 + 4-pin ATX main power cable connector)

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

(Also gives you information about the color code of the wires)

The middle photo shows you a view of the Front of the connector.
The photo to the right shows you the Back of the connector.

Where the wires go down into the connector is a Socket Hole.
At the end of each wire is a metal pin connector. A Male pin connector.

This metal pin connector is shaped like a tube on the end, and comes up to a square shape as you go up.
The square shape fits the square socket hole.

On one side of the square shape is a Tang. It's part of the square metal shape, and sticks out away from the square shape.
Resembles a barb on a fish hook.

In this crude illustration, let a small L represent the side of the square shape, and this forward slash - / represent the tang.

l/

This is an illustration from a manufacturer that supplies this type of metal Male pin connector,

http://www.molex.com/molex/products/datasheet.jsp?part=active/0002092166_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US

A needle with the proper thickness so it won't bend, is inserted into the Front side of the socket hole, and is used to depress the Tang.

If you look down into the back of the connector, and into an individual socket hole with a bright light, and a magnifying glass, you will observe that the square socket hole has a small notch in one side.
This is where the tang slides down into.

It isn't easy to see from the front side.

The tang is depressed using the needle from the FRONT of the ATX main power cable connector, and the wire is removed from the Back side of the connector.

The metal pin connector's tube shape only goes up so far, then it turns into a square shape.

The socket hole in the connector is shaped to match. Tube shaped hole at the front of the connector, square shape coming on up to the back of the connector.

The square shape's corners, of the metal pin connector, keep it from coming out of the Front of the ATX main power cable connector.

The tang keeps the metal pin connector from coming out of the Back.
