Are you sure that your power supply is good, try to short the GREEN and GRAY pin if the power supply fan is running the fan is ok but if the fan not running you need to replace the power supply. I the Power supply is good try to remove the cmos jumper and open the computer then return again the jumper. If you can't hear a sound beeping try to remove the processor and insert again maybe the processor pin or lock is loosen .

No beep at start up

Could be a grounding issue. Remove the mother board from the case, and place on a piece of cardboard. Plug in the power supply, memory, monitor and power switch if it will reach (if not then you will need to short the jumper were the power switch plugs in with a small screw driver). Once set up, power on the mother board, you should get a no hard drive error, since we did not plug it in. If this does work, you will need to go the hardware store and pick up some rubber or paper washer to place between the mother board and the case.

What pins are the switch to turn on power supply continuously

Pins 16 and 17 for a 24-pin ATX main power cable connector, and Pins 14 and 15 for a 20-pin ATX main power cable connector.

1) 24-pin ATX main power cable and it's respective connector,

2) 20-pin ATX main power cable and it's respective connector,

Just remember; The Green wire is the Soft Power On wire, (PS_ON)

ANY Black wire is a Ground wire.

A jumper wire is used briefly to touch the green wire to ANY black wire.

The preferred jumper wire is a paper clip because of it's size. (Diameter)

The jumper wire goes down into the BACK of the connector, RIGHT NEXT TO THE EXISTING WIRE that is already in there.

The BACK of the connector is where the wires go in. (In the links above look at the photo to the far right)

The 24-pin, or 20-pin ATX main power cable, is plugged into the motherboard.
The Power Supply is plugged into power.

The jumper wire goes down into the socket hole, right next to the existing wire, and far down in the socket hole.
It has to touch a metal terminal that is in the FRONT of the connector.
Each wire going into that connector has a metal terminal at the end of it.

Black plastic electrical tape is wound around the middle of the U shaped paper clip.

Use the jumper wire and the Power Supply comes on?
You have a bad Power On switch.

Power Supply does Not come on?
You have a bad Power Supply

Just got mobo and set, fan doesn't start, mobo doesn't give any sound nothing moves....did basic removal of mem and unneccesry one by one and still nothing...

Power. Start with power.

1) Make sure the 24-pin ATX main power cable is plugged in tightly to the mobo.

Ensure that the lock on the male connector (Power cable) is snapped over the tab on the female connector. (Mobo)
Push down on each wire to ensure it's metal terminal connector, is plugged on tightly to each pin.

Looking at the middle photo you are looking at the Front of the connector.
Looking at the photo to the far right, you are looking at a side shot, and the back of the connector. The back is where the wires go in.

Each wire ends in a metal terminal connector.
The metal terminal connector is shaped like a tube, so that it will slide on the pins in the mobo's ATX main power connector.

The metal terminal connector also has two locking tabs. One on each side.

Sometimes there may be a problem with the locking tabs. The metal terminal connector is not tightly on the pin. May not even touch the pin. Check each wire in the 24-pin ATX main power cable's connector. Push in on each one.

Everything is fine so far?
Perform the diagnostic test to see if the problem is the Power On switch, or the Power Supply.

Use a jumper wire on the back of the 24-pin ATX main power cable's connector.
Touch the jumper wire from the Soft Power On wire to ANY Ground wire.

The Soft Power On wire is the Green wire.
ANY Black wire you see is a Ground wire.
(Soft Power On is also abbreviated as PS_ON)

The general type of jumper wire used is a paper clip.
Thin, and stiff, plus a conductor of electricity.
The paper clip is straightened out, then bent into a U-shape.

Black plastic electrical tape is wrapped around the middle of the U.
This area is for you to hold onto the jumper wire.

The 'legs' of the jumper wire, go down into the appropriate socket holes, in the BACK of the 24-pin ATX main power cable's connector.

One leg goes down into the socket hole with the Green wire (PS_ON), and the other leg goes down into a socket hole with ANY Black wire.

The paper clip goes down into the socket hole RIGHT NEXT TO THE EXISTING WIRE that is already present.
Slides down right next to the wire, and touches the metal terminal.

The metal terminal is pretty far down in there.
Ensure that the paper clip is touching both metal terminals on the Green wire, and any Black wire.

Power supply comes on? You have a bad Power On switch,

Power supply does Not come on? You have a bad Power Supply.

If do not hear any beep then it means that the mother board is dead you can try clear the BIOS by removing the battery of the mother board for 5 mins or by shorting the jumper for clearing the BIOS if that didn't help then you have to repair the board or replace it.

I have one sitting in front of me , unfortunately I cannot get it to you but will be happy to tell you the positions. It's not very difficult to fix and I will stick by until you get it correct. I hope I don't complicate this in an attempt to keep it clear and don't be insulted by my answer. I am guessing you don't have a great deal of experience working inside the box and it can become confusing. This is much easier than the length of this answer suggest. You will do this in about 30 seconds, move anything that is in you way and make a note of where it came from. If your hand is small you are lucky but don't force anything and if you are pushing on anything trying to get down there see what it is before pushing more. Better to move it.

There is a front panel connector that is on the bottom right of the board if you orientate the board by placing the computer access panel in front of you with the front of the computer facing to your right. Then right below the floppy disk controlled socket (the smallest flat cable in the box) if no floppy the empty socket below the battery.
There is a double row of pins, looks like 2 rows of 10 pins each. Mine are multicolored, pink and green etc. and the should be marked + and minus, at least plus. The number 1 pin is on the left. The 1 pin is actually the bottom left and the 2 pin is above it. Back down to the bottom row and pin 3 is right next to 1 and the 4 pin right above it. Pin 3 is the second pin on bottom left. Follow the way it goes? The bottom is 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 and right above 2, 4, 6, 8, 10, 12, 14, 16, 18, 20.

Pin 2 is + so put your Power SW on pin 2 and 4 with the colored wire on pin 2. Colored wire in the pair should be positive, and it can be blue, red, green, mine is red and white.
The Power LED goes right next to the Power SW on pins 6 and 8, the colored wire on pin 6, mine is blue and white. And finally the HDD LED goes on pin 7 and 9. All counting from the left to right. My pins are not marked as I think its not critical how the LED is connected and if it does not light then reverse those 2 pins. My colored wire is on pin 7 and its blue. May as well finish, the Reset button is wired to pins 17 and 19 with 17 being positive and the speaker if you have one hooked up (your tiny internal speaker not for listening to music) is a 4 pin connector with the middle 2 sockets empty and fits over the last 4 pin s on the bottom right. 13, 15, 17, and 19. Pin 13 is +. There may be other wires but I don't know where they go depends on what they are but this is what you need. Good luck. And make sure all is unplugged and touch the box to ground yourself or wear a strap. Look but don't touch is a good rule for now.
