You need to track the wires from the case front panel to thier locations: one will be your power switch, one your reset, one hard drive activity light, and one your power light. You want to note and label which light or switch they go to then go to the new motherboards manual and plan which wires need to go where.
the front panel switches : reset and power switch- these are momentary switches so it doesnt matter which way they go.
hard drive activity and power light- these should have a colored wire and a black or white. the colored wire will be your + side.

Why is my hp pavilion a1220n product number ED904AA-ABA?


Try removing the 512 MB memory to see if it does work with the 1GB stick only.

It's not the power supply that does have a problem. It has something with your memory stick.

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.

The tower nor keyboard wont come on and its pluged in


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,

http://www.directron.com/atxswitch.html ]

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

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

(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)

No power cannot turn on


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.

(Generic ATX Power On switch that I have found fits many computers,

http://www.directron.com/atxswitch.html

{The Power On switch, is located inside the plastic Power On button assembly}

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.

(Example of a 24-pin ATX main power cable, and it's respective connector,

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

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.

Dell tower desktop Dimension 5100. Tower makes whistling sound.


sounds like it could be a bearing in your hard drive. is this problem constant? If so, I would open up the tower and disconnect the hard drive and then power up the tower again. if the sound goes away--you need to get a new hard drive. If not, you could have some dust bunnies in your cooling fan.

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.
