In most cases, no, that won't fry the motherboard. It might not boot, but shouldn't fry it. If you're getting no response from the board at boot, make sure you have the CPU fully seated in its' slot. Make sure those front panel wires are in the right place, too - especially the power switch and reset switch. Give it a shot, and see if the board is getting power - are any of the fans running? The thing is, make sure you have that power switch connector on the right jumper, and turned the right way (positive where it should be).

If you have any further information, I could make a better guess, but for now... good luck.

    You don't need either the HD LED or the Power LED to boot the system. What you DO need is the Power Switch, and make sure it is lined up properly, positive prong to positve socket. The only two connectors that actually do anything are Power and Reset. I've never seen a front panel connector that's three prong - LED's only use positive and negative. Does that three-prong plug have 2 or three wires coming out of it? If it only has two, then one of the holes is essentially a dummy, so you'd treat it like a two prong connector, anyway. If you have a model number for the case and motherboard, I could give you more specific information, though I know that's hard to find, especially with a case.

    But, to recap, the Power LED and HD LED are just indicators - they don't have anything to do with the system booting. The primary one to be concerned with is the Power connector, as it will determine whether or not the board is getting power, depending on it you push the switch or not. You have to be sure that one is connected correctly. Sorry to hear about the CPU. That would definitely cause one not to boot. Once you are sure you have a good one installed, connect the power switch and see what happens.

Motherboard


The front of your computer is the Front Panel

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

What you are asking for is a Front Panel header pinout.

I do not have the exact Front Panel header pinout, for your motherboard.
Tell you what I do have though..........

Looking at the Front Panel header on the Ebay link, for the Winfast 760m02-GX-6LRS; the Front Panel header looks to be below the CMOS battery, and close to the Bottom edge of the motherboard.

(Motherboard installed in computer case)

Black rectangular strip of plastic, with contact pins sticking up.
Also looks to be a GENERAL set-up for all Winfast motherboards.
(COULD be wrong here)

This is what I am referencing off of,

http://www.devhardware.com/c/a/Motherboards/Foxconn-Winfast-NF4SK8AA8EKRS-Motherboard-Review/3/

Go to the third photo down. Here you see the Front Panel wires, connected to the Front Panel header; on the motherboard.
(Below round CMOS battery)

Note that the contact pin on the Bottom row, and all the way to the Right; is NOT being used.
(I'm using a 26 inch HDTV as my primary monitor, so it may be easier for me to see)

Now look at this Front Panel header pinout, for another Winfast motherboard,

http://www.techsupportforum.com/forums/f15/winfast-mobo-front-panel-connection-558456.html

(Scroll down a little)

PWRLED is for the Power On LED (Light)
PWRSW stands for Power On switch
HD-LED stands for the HarDDrive activity LED (Light)
RESET stands for a Reset switch, IF USED.

Note where it has a Positive ( + ) sign, next to the pin for the PWRLED.
This is the pin the + wire from the Power On LED connects to.
It is the SAME for every LED that connects to the Front Panel header.

Let's number the contact pins, to make the explanation easier;
Starting at the Left side, Top row; going towards the Right;
Pins 2, 4, 6 and 8. There is NO Pin 10.

Starting on the Left side, Bottom row; going towards the Right;
Pins 1, 3, 5, 7, and 9.

Pin 2 is for the Positive wire.
Pin 1 is for the Positive wire
If the LED's are dim, (PWRLED, and HDD LED), OR; the LED's do not light up, switch the wires around.

(Pin 9 is N/C.........Not Connected. This is probably a 5 Volt test point, that was used by the factory)

There is a method you can use though, and find out what the individual contact pins are, in the Front Panel header;

Use an LED with two wires

Computer (Power Supply) plugged into power, go along the top row, and touch two pins at a time, with the two wires of the LED.

Example; Pins 2 and 4, as shown in the pinout.
Did the Power Supply come on?
No?

Go to the next two pins. Try again.
When the Power Supply comes on, you naturally know that is the two contact pins; for the Power On switch.
DO NOT touch them again. In fact connect the Power On switch wires.

Power Supply on, computer running;
Now go back along again;
1) LED light blinks?
You have the HarDDrive activity LED, contact pins.
2) LED light stays on?
You have the Power On LED, contact pins.
3) Computer restarts?
Those are the Reset switch, contact pins.

4) Nothing happens?
May be contact pins for a speaker, or contact pins that are not used.
(Speaker is for hearing BIOS Beep Codes.
You have a Piezo buzzer, to the Left of the CMOS battery; for that)

Post back in a Comment, as to the results.

If possible, I would like to ask upon you; to post the Front Panel header pinout; when you find what it is.

That way when a person in the future also has this same problem; the solution will be posted on the internet, for them to find.

For additional questions please post in a Comment.

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires connect to, is the Front Panel header.
(Power On switch, Power On LED, HarDDrive activity LED, etc)

The Front Panel header is Black, rectangular in shape, and is situated in a vertical position; located in the Bottom Right corner of the motherboard. (Next to the mounting hole)

It is a standard 9-pin HP Front Panel header,

http://h30434.www3.hp.com/t5/Desktop-Hardware/Getting-a-new-case-i-need-Front-Panel-pinout/td-p/842897

Scroll down to the 9-pin Front Panel header photo, and pinout.

The 4-pin side is the EVEN side. Pins 2, 4, 6, and 8. There is NO Pin 10.
The 5-pin side is the ODD side. Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED. (Light Emitting Diode, so it is redundant to call it a light)

Pin 1 is for the Positive ( + ) wire.
IF the HDD LED is dim when the harddrive is active, (IN use), switch the wires around.

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

C) Pin 9 is N/C. Not Connected. Reserved for factory use, and it is +5 Volts.

D) Pins 2 and 4 are for the Power On LED.
Pin 2 is for the Positive ( + ) wire.
If the PWR LED is dim when the computer is on, switch the wires around.

E) Pins 6 and 8 are for the Power On switch.

Scroll the HP Support Motherboard Specification page down. Click on the + sign next to Motherboard Layout.

Left to Right on bottom edge of motherboard, Internal Connectors;

AUDIO_1 is for the audio ports on the Front Panel.
ATX_IN is where the small audio cable from the optical drive plugs in.
(CD/DVD drive)
IF TWO optical drives are used; the Main, or Primary optical drive, is connected with the small audio cable. NOT the secondary optical drive.

HD_AUDIO also connects to audio ports in the Front Panel.
May be mistaken, but don't believe SPDIF_OUT header is used.
1394A1 header is for the Firewire ports in the Front Panel (1394a)
USB 2 and USB 4 headers are for the Front Panel USB ports.
USB 1 and USB 3 should be for a Card Reader.

Need where the power cables go, and what they look like? Just post back in a Comment.

Proper installation of tower wires


According to Gateway Support, the Gateway 505GR desktop computer uses an Intel (Ausberg) 915G motherboard,

http://support.gateway.com/s/PC/R/3724/3724iv.shtml

Intel (Ausberg) 915G motherboard,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

Scroll down to the photo with the sections marked in red.

In the top link, looking at the motherboard with the computer case open, the USB and Firewire (1394a) cables, can be seen attached to the motherboard near the letters D, E, and F.

In F that red cable is a SATA cable. One end attaches to the back of the SATA harddrive, (The angled end), and the other end of the SATA cable attaches to one of those SATA headers on the motherboard.
(SATA header = SATA connector on motherboard)

Preferred SATA header for the Harddrive is SATA 1.
DOESN'T matter though. That's the beauty of SATA. You can plug the SATA data cable into ANY SATA header on the motherboard, and BIOS will find the harddrive.


In the second link, looking at the motherboard photo shown, and comparing it to the view of the motherboard as mounted in the computer case, the Front Panel header is at the very Bottom Right.

Two rows of pins in a White rectangular shaped header,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

(S points to Front Panel header)

[ The plastic front of a desktop computer is the Front Panel.
The area of pins on the motherboard, that the Front Panel wires go to, is the Front Panel header ]

A) Top row has Even numbered pins
B) Bottom row has Odd numbered pins.

http://www.intel.com/support/motherboards/desktop/sb/CS-009016.htm

1) Power LED = Power On LED light
2) Hard Drive Activity LED = LED light that flashes (Usually red in color) when your harddrive is active. Being used.
3) Reset switch = Reset Button. The Reset switch is behind the Reset button. (IF the computer uses a Reset switch)
4) Power Switch = Power On switch
5) Forget about Pin 9. That's for 5 Volts DC - Out. Used by factory.

Which wires coming out of the Front Panel, are the Power On wires, Harddrive LED light wires, Power On switch wires, etc.?

Remove the Front Panel, and trace where the wires end.

IF, the wires already installed coming from the motherboard to the Front Panel, are Too short, you should make notes before you remove them from the motherboard.

Note what color pair of twisted wires, went to where, in the Front Panel.
Compare to the chart of the Front Panel header given above.
(IF any wires are still connected to the Front Panel header on the motherboard)

Once the Front Panel is removed, it's usually pretty easy to trace the two wires up to the Power On switch.
Same for the Power On LED light.
Again, same for the HarDDrive activity LED light.

The SATA harddrive requires a DATA cable, and a SATA power cable.

The connector for a Data cable has 7 contact pins. It is the shorter connector.

http://en.wikipedia.org/wiki/File:SATA_Data_Cable.jpg

The connector can be at a 90 degree angle as shown, or a straight connector.
IF the data cable has an angled connector, it plugs into the Harddrive.
Straight connector goes to the motherboard.

The connector for a SATA power cable has 15 contact pins. It is the longer connector,

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

Note the L shape of the connectors for the SATA data cable, and SATA power cable.

Also;
This is a 4-pin standard Peripheral power cable. Commonly misnomered as a 'Molex' power cable,

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

IF, the SATA harddrive has a provision for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY use just the SATA power cable.

Using both power cables will burn up the harddrive.
May not happen immediately in some cases, but WILL eventually happen.

Hello i need to know how to reconnect the computer case wires to a sr1703wm compaq motherboard


Hello.

The Compaq Presario SR1703WM desktop computer, uses an Asus A9AE-LE motherboard.
HP/Compaq's name is AmberineM - GL6E

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00496280&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=1815742

1) I would like to start with the Front Panel wires.
The Front panel, is the plastic front on your computer tower, where the Power On button, Power On LED, and so on is located.

The Front Panel header is the connector on the motherboard, where the cables, (Wires), from the Front Panel connect to.

Looking at the HP Support link above, I would like you to scroll down the page to the illustration of the motherboard, and the photo of the motherboard under the illustration.

Looking at the illustration observe the bottom Right corner.
F_PANEL1 indicates the Front Panel header.

Note there are 4 pins going across the Top, and 5 pins going across the Bottom.

Looking inside your computer, the motherboard will be located in a different position, compared to the illustration.

The Front Panel header will be located Vertically, (Up, and down)

Note that there is a twisted pair of Black, and Red wires.
These wires form the Power On cable.
They come directly from the Power on switch.

There is a twisted pair of Yellow, and Black wires.
These wires form the Harddrive Activity LED light cable.
(HDD)
When the harddrive is active, this LED flashes.

There is a twisted pair of Green, and Black wires.
These wires form the Power On LED light cable.

The wires, (Cables), should be in one Black connector.

Looking at the Front Panel header in your computer, align the Black plastic connector's socket holes, with the pins sticking up out of the Front Panel header, on the motherboard.

Note that the Front Panel header is rectangular in shape. There is 1 pin missing.
The Black connector coming from the Front Panel of the computer, has one socket hole blocked off, to match.

Align the four socket holes in the Black connector, to match the 4 pins sticking up out of the Front Panel header, on the motherboard.

The other 5 socket holes in the Black connector, will match up to the 5 pins sticking up, automatically.

Use care, and you may need a bright light to assist.
These pins can be bent quite easily.
(Also watch your fingers, as the ends of the pins are S-H-A-R-P!)

2) Where it states CLRTC (CLPWD under it), is the Clear CMOS jumper.
Suggest you leave it alone.

3) Where it states F_ USB1, and F_USB2, is where the USB cables from the front of the computer connect to.

(The USB ports on the front of the computer's Front Panel.
F_USB1, and F_USB2 headers on the motherboard, are shown on the illustration to the Left, of the Front Panel header. F_PANEL1)

The plastic connector on a USB cable coming from the Front Panel, has an orientation just like the Front Panel header cable does.

There is 1 pin missing on the USB header on the motherboard.
There is a blocked socket hole in the USB cable's connector.
Align the connector to match the pins.

Doesn't matter which USB cable from the Front Panel, that you connect to the USB headers on the motherboard.
BIOS will find them, and assign an IRQ to each, once you turn the computer on.

All you will see at a first glance is a series of thick Gray insulated cables, coming from the Front Panel of your computer.

If you follow the cables by eye, you can see where the USB cables are connected to the back of the USB ports, on the Front Panel.

You may, or may not, have to remove the Front Panel to see more clearly.

Computer case open, look inside towards the Front Panel.
There is a Green plastic tab towards the Top.

This locking tab is depressed Towards the Inside of the computer, to START to unlock the Front Panel.

Towards the bottom in the same plane, is a Black locking tab. This tab is pulled Towards the Outside of the computer.
There is another Black plastic tab on the opposite side.

At the Bottom are two more Black plastic locking tabs. These are depressed down, towards the Bottom of the computer case.
One on one side, one on the opposite side.

Start by depressing the plastic Green tab, and gently easing the Top of the Front Panel, slightly out.
Then go to the two Black plastic locking tabs located towards the Middle, and depress them.

Ease the top of the Front Panel out a little more.
Finally go to the two Black plastic locking tabs located at the Bottom, and depress them.
Ease the Front Panel off.

(NOTE*
Your computer's Front Panel may not have locking tabs located at the bottom.
Just locking tabs located up from the bottom, more towards the middle)

It's no picnic for your first time, but once you have done it, it becomes easy. (Ummm, Easier!)

4) The Firewire (a1394) cable on the Front Panel, connects to the F_1394 header on the motherboard.
In the motherboard illustration the F_1394 header is located to the Left, of PCI2

Need any further cable connections, post in a Comment.

2) Observe anti-static precautions.

Your body carries Static electricity. Static will fry out (Short Circuit) the hardware components inside of a computer.

Touch the metal frame of the open computer case, to relieve your body of static. (Should you get up, and leave in the middle of working on your computer, upon your return Touch the metal frame again )

Alternatively you can purchase an ESD wrist strap, (Electro Static Discharge), and use it. Average cost is around $6. The alligator clip is attached to the metal frame of the open computer case.

3) Identify each cable (Wire) that comes from the Front Panel, and goes to the motherboard.
Make notes, and a sketch of what pins on the motherboard those wires go to.

You may be just replacing the Power On switch, but if any of the other Front Panel cables are accidentally disconnected, from the Front Panel header on the motherboard, you won't have information as to where they go unless you make notes, and a sketch.

[The Front Panel is the plastic panel on the front of your computer, that has the Power On button, Power On light, HarDDrive activity light, etc. The Front Panel header, is the connector, or the pins on the motherboard, where the Front Panel wires go ]

This is HP Support, and the main page for the Pavilion a1600n Desktop PC,

http://h10025.www1.hp.com/ewfrf/wc/product?product=3245022&lc=en&cc=us&dlc=en&submit.y=7&submit.x=10&lang=en&cc=us

To see the Front Panel header, there is a photo of the motherboard, and an illustration. On the above main page click on - Product information
Then click on- Product specifications, and finally on - Motherboard specifications A8M2N- LA (NodusM3)

Scroll down the page to the motherboard illustration.
In the very bottom right corner of the motherboard, you will see the Front Panel header, F_Panel 1

The Front Panel will have to be removed to access the Power On switch. This is the time that the cables from the Front Panel, can be easily accidentally disconnected from the Front Panel header on the motherboard.

How to open the computer case, and how to remove the Front Panel, can be found in the Upgrading and Servicing Guide.

On the main page click on Manuals.
Now click on - Upgrading and Servicing Guide - 2.86M. This is a PDF file download. Takes a few seconds to see the first page.

The Power On switch is located inside of the plastic Power On button. The plastic tabs of the button are gently eased to the outside, and the Power On switch is slipped out.

The plastic may have become brittle over time due to age, and heat from inside the computer.
I find using a hair dryer set to low heat, and moving back, and forth across the plastic, helps soften the plastic of the Power On button, enough to remove the PS_ON switch more easily.

This Power On switch should be a good replacement,

Problem with microphone


most of the old motherboards dont support the audio and mic port to work both in back side(back panel header) and front side (front panel header)simultaneously...

most of the old motherboards dont support multi streaming so you cant make both the back panel header and front panel header to work at a time ie i mean you cant connect both panel header at a time ...

you can just refer to your motherboard manual for the detailed information about it ..

in your motherboard if there is any option to connect the front panel header to the motherboard other than the back panel header you can connect it to that the detailed pin information will be given in the motherboard manual ..

if you dont have the option in the motherboard to connect the front panel header seperately then you must remove the pins connected from the back panel header and you must insert the front panel header pins .
this will disable your back panel audio ,mic,linein functionalities but you will be able to connect in front panel header , this front panel header will work ..

if the motherboard is not compatible then the system assembler will leave the front panel wires not connecting to motherboard ..

like this only one panel can work at a time ,
but in the latest motherboards the multi streaming technology has been introduced so both the panels can work at a time and can play different audio on 2 different panels ...

thank you
bye
any doubts you can reply me
i am always here to assist you
please rate my solution
have a nice day

Front panel connector


First of all remove the front panel connectors before powering up, cause U do not want to put any wires to the USB headers. In doing so u might damage u'r board Second get your hands on the mother board manual,, if the front header has no label printing indicating the connection details. If no manual. then get on line and do a google search you'll find plenty of info's on how to DIY. Happy hunting Rifaa
