All I see for the heading, romakavati, is - Fujitsu Barebone Systems.

Do I assume we are talking about a barebone Desktop Computer?

If so;

1) The plastic front of the desktop computer is the Front Panel.

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

Do you have the wires from the Power On switch, connected CORRECTLY, to the Front Panel header?

(The Power On switch is located inside the plastic Power On button assembly. It is a style of ATX power on switch.

This is one example,

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

2) Your motherboard may require a 4-pin ATX +12 Volt power cable.
Example of cable,

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

This is power for the Processor.

If your motherboard does require it, do you have it plugged in?

3) Do you know if the Power Supply is good?

Even if it is a new one, and came with the barebones computer you bought, it doesn't mean it is a good one.

May be a bad one, and doesn't even turn on.
May be a bad one, and one of the three main voltage power rails, is no good.

[ There are three main voltage power rails, in the Switched-Mode Power Supply, installed for your Fujitsu desktop computer.

A) The 3.3 Volt power rail

B) The 5 Volt power rail

C) The 12 Volt power rail

All are DC Voltage.

{In comparison two D cell flashlight batteries store 3 Volts DC. Just a fact you may be interested in ]

First see if the Power Supply will turn on. This is done with a jumper wire, on the Soft Power On wire, in the ATX main power cable's connector.

Your ATX main power cable may be a 20-pin ATX main power cable, or a 24-pin ATX main power cable,

A) 20-pin ATX main power cable,

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

B) 24-pin ATX main power cable,

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

With both power cables you will see there is a Green wire.
This is the Soft Power On wire.
Abbreviated as PS_ON.

A jumper wire is used to briefly connect the Green wire, to ANY Black wire.
ALL Black wires are Ground wires.

DO NOT cut the wires, or poke a hole in their insulation.

The preferred jumper wire is a paper clip.
The paper clip is straightened out _________________
,then bent into a U-shaped.

The middle of the U is wrapped a few times, with black plastic electrical tape. This area is for your fingers, and thumb to hold onto.

U-shaped jumper wire turned upside down, you have two 'legs'.
The legs go down into the socket holes, of the ATX main power cable's connector.

Let's look at the example for the 24-pin ATX main power cable, again,

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

The 24-pin ATX main power cable needs to be plugged in, as shown in the photo to the far right.

Computer power supply is plugged into power.

One leg of the paper clip jumper wire, is inserted down into the socket hole, RIGHT NEXT TO the Green wire.

Goes down in the socket hole, slides past the insulation of the Green wire, and touches the metal terminal at the end of that wire.

The leg of the paper clip jumper wire, MUST go down in the socket hole far enough, to TOUCH that metal terminal end.

[ Metal terminal is a type of female Molex terminal. Tube shaped, and goes over a contact pin in the motherboard connector,

http://www.molex.com/molex/products/datasheet.jsp?part=active/0002081202_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US ]

The other leg of the U-shaped paper clip jumper wire, goes down into
ANY socket hole, that has a Black wire in it.
ALL Black wires are Ground wires.

The contact made is no more than 2 seconds.
(The Power On switch is a Momentary Contact Switch)

IF, the Power Supply comes on, you either have a bad Power On switch, or it is Not connected correctly, in the Front Panel header on the motherboard.

IF, the Power Supply does Not come on, you have a bad Power Supply.
Plain, and simple.

IF, due to lack of a more detailed statement from you, that your problem is the Power Supply DOES come on, but Windows does not load;

A) You know the Window operating system is NOT on a new harddrive, right?
You have to install Windows on it.

B) Installing a harddrive with Windows already on it.

You know that when Windows is installed on a computer, (To the harddrive, actually), it assigns hash values to certain major components, right?

Certain major hardware components such as;
1) Processor
2) Motherboard chipset
3) BIOS program, and version.
4) Harddrive
5) Graphics chipset

Change any two, or more of these components, and Windows will want to be activated again. (Not registered,... Activated)

This is because Windows will 'think', you are taking it off of the harddrive it is on, and trying to install it on another harddrive, or computer.

Microsoft User's License states; "One GENUINE copy of Windows per
ONE computer"

[ Microsoft makes one Master disk. From it all GENUINE copies are made, and sold to the consumer ]

However, the Windows activation screen does NOT always come up.

Ready for your questions, and additional information you did not post.

Need front panel pin colour code


The two green cables are for power LED, one + and one -. Then there are two yellow cables for the HD LED, with one + and one -. The red ones are for ON/OFF (power button), and the blue are for reset. So yeah, you are technically right if I understood what you said xD

No monitor signal


make sure pc is off ,make sure video card is seated properly if it is try resetting cmos there is 3-pin jumper ususlly by battery and usually says reset cmos by it I have seen many differences according to mobo this can also be accomplished by taking out the mobo battery (the little round silver battery) if you have jumper take off 2 pins its on know put on other 2 for 1min then put back turn on, if removing battery take out then turn on pc

No boot up.


Power supply is easier to troubleshoot my local pc shop has used ones for $5 or if you have one laying around make sure you have one with the proper mobo connector 24pin will sometimes fit 20 pin as long as there are no transistors to close to plug just turn pc off unplug all drives and mobo plug in good supply and turn on if it works thats the problem if not probably mobo

Loss of power to onboard USB and PS2 ports


Hi, I checked a known good spare motherboard with a VOM (continuity tester): pin 4 of the KB PS2 port, pin 1 of the rear USB, pin 1 & 2 of the front panel USB onboard connector, pin 3 of the infrared, pin 4 of the speaker connector, pins 4, 6,21 & 22 of the ATX 24-pin Power Connector are all interconnected (+5VDC). If that is an indication of the general +5 supply layout, you can probably hard wire a new +5 supply line to where the +5 is gone from where it is still available. Of course without a schematic, I might be off. Determining the actual component position of the surface mounted fuse (or fusible link) might not be that easy since manufacturer do not publish such information loosely. A shotgun approach (test all) would be time consuming but of course challenging. Your best bet would probably be as mentioned earlier, hardwire and install in series with the new +5 line a low amp (500ma or lower) smfuse. This article describes the power requirement of USB ports > http://pinouts.ru/Slots/USB_pinout.shtml. Hope this be of some help to you. Pls post again how things turn up. Good luck and kind regards.
