WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.
http://www.kitchentablecomputers.com/static.php - rules
Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.
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.
Remove the memory modules from their slots.
Take the opportunity to clean the slots on the motherboards and the memory module connectors.
Use compressed air to blow dust away and clean contacts with a soft cloth.
Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components.


Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r
Allow the pins to dry.
They will air dry in a matter of minutes
If reseating the memory did not resolve the issue try swapping the location of the memory.
If you have only one stick of memory in the computer try moving it to another slot and then boot the computer.
Check the memory module and memory slot contacts.
They are either copper tin or gold.
The colour will tell you which they are.

Mixing tin and gold can result in corrosion that prevents proper contact.
Look for any sign of physical damage to the memory module, memory slots or the motherboard.
Reseat the memory modules.
You should hear an audible click when they are in place.
Do not use too much force to reseat the memory module in to the slot this can cause damage to the module, slot or motherboard.
The hardware that you are trying to access is damaged or failing.
Could be a problem with the Hard Drive or the Hard drives PCB
http://www.onepcbsolution.com/
http://www.youtube.com/watch?v=du0Qd_3wFWM
There is a connection problem such as a bad cable

Test all power and data leads that attach to your hard drive SATA

the leads from your MOTHERBOARD TO THE HARD DRIVE make sure they have a
secure dust free connections and are not faulty.
Although it would be very rare for the sata lead to be faulty.
Make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty
Computers need power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error

SOURCE: Proper pin numbers to install inserts in a Dell SATA 34 pin GX270 motherboard

why do you need the IDE cable pin out if you are using SATA?
they are diiferent and not interchangeable. if you want to use IDE pin out for SATA, then you need to get a adapter from IDE to SATA.

Hi there.
Get a strong flashlight and a magnifying glass (if you have one). On the motherboard look for the front panel, it should be marked PWR and coloured green, also the plug that connects to it should be marked PWR_SW. On some boards there are no colours but the markings are the same, so take a good close look.
Have a look at these pictures for an idea >>>>>>

But it doesn't look like it will be much help because it appears the connection from the stock case is custom. If you have the original case you can trace the wires.

Hi Greeneyedbj,

What kind of I/O connectors are you looking for *********** board sir?

pcsyke_138.jpg

The image above has the following for your I/O connectors.
1. Three usb headers up to 6 additional devices, most casing can support 2-4 pins. 2. Front Audio Connector. 3. Front Panel Connector. Power Sw, Reset Sw, Powed Led, HDD Led

Branded casing has the following I/O connectors.
1. Esata 2. Firewire (Dont use the USB headers, firewire use a different pin-layout) 3. Chassis Intrusion Alarm Header.

Hopefully this information helps.
You can ask for more help.

Photo of the Asus M2N78-LA motherboard,

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=c01421635&dlc=en

This photo also shows the orientation (Direction), that the motherboard is sitting in a computer case.

To the very bottom right is the Front Panel header.

The front plastic panel of the computer is the Front Panel.

The area of pins on the motherboard that the cables, (Wires) from the Front Panel connect to, is the Front Panel header. ( F_PANEL )

The Front Panel header, is the black rectangular shaped plastic block, that is sitting vertically on the motherboard.

Has two columns of pins.
4 on the left side, 5 on the right side. Makes it look as though there is a pin missing, at the top left corner.

I'm going to number the pins.

Pins on the Left side starting at the Top, going down;

Pins 1, 3, 5, and 7.

Pins on the Right side starting at the Top, going down,

Pins 2, 4, 6, 8, and 10.


A) Pins 1 and 3 are for the Power On switch. (Power On button)

B) Pins 5 and 7 are for the Power On LED light.
Pin 7 is for the Positive ( + ) wire.
(If the LED light is dim, reverse the wires around)

C) Pins 4 and 6 are for a Reset switch, IF a Reset switch is used. (Reset button)

D) Pins 8 and 10 are for the HarDDrive activity LED light.
Pin 10 is for the Positive wire. ( + )
(If the HDD LED light is dim when operating, switch the wires around)

Pin 2 at the top Right is NOT used. (NC. Not Connected)

For additional questions please post in a Comment.
I am looking at a motherboard manual in PDF file form, for the Asus M2N78-LA motherboard.

Model name BLUFORD. E139765 motherboard. I need J16 pin layout for the power switch, reset switch, etc. Dell is not very helpful with this paticular board for some reason. Thank You for any info. DW


This is what I found after extensive searching,

......................O
.PWR LED- O O
.HDD LED- O O HDD LED+
.................... O O
.................... O O
.................... O O PWR LED+
.................... O O
...PWR SW O O PWR SW

Looks pretty lame, huh? I found this on Dell's Community Forum.
I gather, this motherboard was used in the Dell Dimension 2350.

http://support.dell.com/support/edocs/systems/dim2350/techov.htm#1101565

Looking, at what Dell has for the layout of the Dimension 2350 motherboard, there are 20 pins in the J16 header, just like he has crudely shown above. I don't see one missing in the corner, though. Of course, the link above is a crude example from Dell.

This person stated it was for the J24 header on the motherboard. Also stated that it was the Front Panel I/O header. (At least that's what was stated) I believe he was confused with the Control Panel header J24. Hopefully it is for the J16 Front Panel I/O header, as it has the Power On switch, HDD activity LED, Power LED, and so on.

Indications are that the O's represent the pins. There was a statement of taking -> Note, that there is a missing pin in the upper corner, and this orients the connector view, Orients, how you are looking at the connector. Only you will know for sure. I don't have this motherboard in front of me. Dell ISN'T giving ANY info out.

This person had the Bluford E139765 motherboard, in a Dell Dimension 2350.

The statement was also made, that there is a Brown jumper wire that connects the two CON CNT pins together, but didn't know if this jumper is required, as this person is putting this motherboard, into an aftermarket computer case. (?)

Solution?
What I would do.
I would have the power supply plugged in. I would use an LED lamp, with two wire leads attached to it. Leads of about two inches long, or more. (Borrow one out of the Front Panel, or from another parts computer?)

Twist the ends of the lead wires tightly. I would then touch the leads to two pins. Should they be power Out pins, (HDD activity lamp pins. Power LED pins, and so on), the light will light up, and not short out the two pins touched.

(If the LED light doesn't light up, no biggie. It just means the wires need to be reversed. Bear this in mind, when you go to hook the LED's up)

When the two pins for the Power On is found, the computer will turn on.

Judging by the crude diagram the missing pin is on the upper right.
Only you will know for sure, as the J16 header should have a flat place in one corner, where a pin would go. NO pin.

If so, this is what I see.

Processor to the left, PCI slots to the right, J16 header on the right, above the PCI slots. The header goes along the edge of the motherboard, lengthwise.

I'll number the pins like this.
Starting at the Top Left, and going down the Left side.
Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19.

Starting at the Top Right, and going down the Right side.
NO pin, (Would have been Pin 2),
Pins 4, 6, 8, 10, 12, 14, 16, 18, and 20

Pins 3 and 4 are for the Power LED. (Confusion here)

Pins 5 and 6 are for the harddrive activity LED. PIn 6 is for the + wire/

NO connection to Pins 7, 8, 9, and 10

Pins 11 and 12 are for the Power LED.
(Which ones to use? Pins 11 and 12, or Pins 3 and 4? I leave it up to you to test as the computer is on, and see)

NO connection to Pins 13 and 14

Pins 15 and 16 are for the Power On switch.

NO connection to Pins 17 and 18.

Pins 19 and 20 are for that jumper wire he mentioned. I would try it without it. If the computer doesn't come on, or something doesn't work, like the harddrive for example, I would unplug the computer from power, then attach this jumper. Plug in, and see if everything works.

How to connect front pannel


How about a picture? Pg. 46 in your manual.
Need manual, download from Intel. (Click on link).
http://www.intel.com/support/motherboards/desktop/RC440BX/sb/CS-013608.htm

Intel RC440BX Specification
Pg. 46
Basic rules case wiring. The color black is considered ground -. Power wires + can be any other color including stripped wires. (This is standard but case Mfg change to their own specification).

Pin 1 is + power for LED Hard drive green LED, Pin 2 is -/ground for Hard drive LED.
(Pin 3 is + power for LED Hard drive yellow LED, Pin 4 is -/ground for Hard drive LED).(See more options on pg. 47).
Pin 5 is + power for case On/off button, Pin 6 is -/ground On/off button.
Pin 7 is + power for Reset Switch, Pin 8 is -/ground for Reset Switch.
Once positive & negative pins has been located each connector follows in suit.

The Intel RC440BX front case connector is in an odd location.
The user will find it hard to connect front case LED connectors while the board in installed into the case.

Good Luck!
