Installed an Upgrated Mother Brd,in my Hp Desktop Tower,but the power Switch receptacle in the New Mother Brd has 16 pns

Motherboard should have the pins labeled. POW+ POW-

Colored wire is + Black is - although the power switch doesn't really matter. Same with the LEDs they can be reversed and it wont hurt anything or work differently.

Maybe you put the wrong jumper of the power jumper for the front panel.

Explanation:
You can see the switch to turn on the PC right, then make sure that switch correctly installed on the right jumper on the board. Follow the cable to attach to the mother board.

Advise, c

1) Check to make sure THE receptacle in the surge protector that the computer is plugged into, is good.
I have had a few surge protectors where just THAT receptacle was bad.

("Hmmm, monitor, router, and printer has power from the surge protector." Checked the receptacle in the surge protector that the computer was plugged into, with a table lamp, found THAT receptacle was bad)

2) Receptacle in surge protector proves to be good?
Suggest performing the test to see if the problem is the Power On switch, or the Power Supply.
(The Power On switch is located inside the plastic Power On button)

The test involves bypassing the Power On switch, by using a jumper wire on the Soft Power On, in the ATX main power cable's connector.
Has nothing to physically do with the switch itself.

Using the jumper wire the computer (Power Supply) comes on?
Problem is the Power On switch.

[ Example of a generic ATX power on switch that I have found fits many computers,

Using the jumper wire the computer (Power Supply actually), does Not come on?
The problem is the Power Supply.
Replace.

(Green wire {PS_ON} is the Soft Power On wire. It is jumped to ANY Ground {Black} wire)

Want to know how to Properly perform the above test? Please post back in a Comment.
Also post the computer manufacturer's name, and the Model Number.
(On the back of a desktop computer next to the Windows Product Key, or up on the side of the tower)

Suggest you check the simple stuff first.

Not checking is akin to a car that won't start, and tearing apart the entire fuel system, only to find it was just out of gas.

1) Make sure the receptacle the surge protector is plugged into, has power. Surge protector Power On light should be lit.

2) Check THE receptacle in the surge protector, that the computer itself, is plugged into.
Have had a number of expense surge protectors, where just THAT receptacle was bad.

("Hmmm, surge protector Power On LED light is lit. Monitor, printer, sound system, and router plugged into the surge protector has power. Should be good to go.

NOT!
Plug a table lamp, or similar device into THAT receptacle.
Make SURE it has power)

Surge protector, and receptacle in surge protector checks out?
Bypass the Power On switch.

See if the problem is a $5 Power On switch, or the Power Supply.

This is information about computer Power Supply's,

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

This is a basic example of an SMPS, (Photo at upper right. You can click on the photo to enlarge), and info about.
(Switched-Mode Power Supply. The main type of power supply used in personal computers),

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

By bypassing the Power On switch, you will be able to determine if the problem is the switch, or Power Supply.

Bypassing the Power On switch turns the Power Supply on?
Bad Power On switch.

Bypassing the Power On switch does Not turn the Power Supply on?
Bad Power Supply.

A jumper wire is used on the 20, or 24-pin ATX main power cable.
The jumper wire goes to the Soft Power On, (PS_ON. Green in color), to ANY Ground wire.
(ALL Black wires are Ground wires)
A MOMENTARY contact is used.

In order to guide you in this procedure, I need to know the computer manufacturer name, and Model Number.

On a desktop computer this will be located on the Back of the computer tower, (Next to the Windows product key), or up on the side of the tower.
Some models have it where there is a door you open in the front, and the product number, or model number is located there.

You a need a pair of identical memory modules must be placed in matching DIMM slots in order to to make it work. They need to be same mfg, everything.

Thanks Mark

reinstall your Windows

The manual in question can be located here

http://download.intel.com/support/motherboards/desktop/sb/d1047103_en.pdf

It is a pdf file, so you will need ADOBE,
I have checked and the pinout for the front panel connectors is there.

i have no mother board cd then system is formatting is not possible please help me i want drivers cd

I've seen several of these. All have been the connector. On the bottom of you on/off switch is what Compaq calls a button board. This board if OK but it plus into a connector on the mother board. If you look at this connector closely with a magnifying glass as you attempt to remove the button board you'll notice that the connector is coming off the mother board. The pins for this connector are almost as thin as a human hair. I don't know of any way to repair this. HP is only illing to sell a new mother brd. Good luck.

The manual you need will be on the board manufacturers web page, howevr I will bet you have the case power switch and perhaps the reset switch on the wrong pins on the mother board. To check this, remove the switch leads from the mother board, then use a small screw driver and bridge the pins on the mother board a pair at a time. All of these leads plug on to the board in a line and not across the two lines of pins. when you get the mother board to fire up by this method geet a torch and look closely alongside the pins you will see the letters PWR SW or RS SW. It does not matter what polarity these two sets of leads are plugged onto both will work. The LED lights on the case front will only work if the polarity is correct but it will not do any harm if they are backwords. On the board you should se two sets of pins marked HDD and PWR these are the led light pins you will know you have them right when the usual red and green lights are working at the front of your tower.
