POWER SWITCH (blk/wht leads), POWER LED (blu/wht leads), and HDD LED (red/wht leads) got removed from motherboard by accident. I know where they should go, but not the sequence. They go to a 4 position male block in lower right corner. Hope you can give me some advice. Thank You

I am assuming you are trying to power up an installed motherboard, based on the category selection. You say that you have power connected. That means that you have connected the 20 (24) pin main connector and the 4 or 8 pin CPU power connector to the motherboard. Have you connected the front panels controls to the motherboard header? There are connections for the power switch, power LED, HDD LED, reset switch (optional). They must be connected in order for the motherboard to start. THe HDD and Power LED connections are polarity-based, so if you hook them upo backwards, their respective LED will not light. The HDD LED plug is usually red and white with the red being on the positive (+) terminal. The Power LED plug is usually green and white with the green wire going to the positive terminal. The power switch and reset switch wires can be connected either way as they are not polarized.
Try looking closely with a magnifying glass for small letters on the motherboard next to the pins. PS= power switch, HDD= Hard Drive LED, RST= Reset, PLED=Power LED. If they are not on the board, you will need the manual that came with your motherboard in order to get the pin-out information you need.You will have to visit the manufacturer's website to download the manual that you need. For your motherboard, the link to the website is:
Once you get to the website, look in the support or downloads section of the site for the model number of your board.and select the manual you need for download. This is a Tiawanese web site and you may have some problems navigating through the site to find your manual.
In the event that you cannot locate the manual, look for a "contact us" link on the website support or home page. This link will provide you with contact information (phone or E-mail) and allow you communicate your problem to them.
Sorry, but I cannot tell you how to hook up your motherboard as each motherbard has different pin locations and the data/power/ front panel cable connectors must be connected properly.
If you get the the manual and have any questions let me know.

Connect the front panel leads to the motherboard connector marked "JFP1" using the following pins as indicated by the markings on the motherboard and the front panel leads: HDD LED on Pins 1 and 3; power LED on Pins 2 and 4; reset switch on Pins 5 and 7; and the power switch on Pins 6 and 8.
I will tell you how wire your case front panel, but before that lets test the motherboard to make sure the problem is not the board itself.
Remove all the wire connections to the front panel.
Turn the power on and with a small screw driver or anything that is metal short (touch) the two pins that are the PWR SW. (look at the list of pins I have put at the end)
If the computer turns on then it means the board is ok.
The following information is also availabe in the motherboard manual available from the gogabyte web site download section
On the motherboard next to the battery is the front panel header pins. it looks like
0 0 0 0 0 0 0 0 i also write them as numbers as well to make it easy for you) 0 0 0 0 0
1 2 3 4 0 0 0 0 5 6 7 8
1 and 2 are message LED. you don't need any connection to this. 3 and 4 are the power switch connections no polarity, just connect the wires 5 and 6 are the hard disk LED. 5 is the positive side (usually red) 7 and 8 are the reset switch. no polarity, just connect the wires. Next to the message LED there is a three pin connection. This is for the power LED.
You can download the manual for your motherboard here.
Inside you will find information of where does each connector go. Each connector on the case has a marking on it (HDD, PWR, RST or similar) which stands for hard disk LED, power button, reset button and so on. Connect it to the right place, and problem is solved.

There are 3 versions of this motherboard; 1.0, 2.0 & 3.3, but the layout is identical.
The general layout is shown in pins.jpg. For the power led, the white wire goes to the (-) terminal either pin 2 or 3, both are MPD- while the green goes to the ( ) or pin 1 (MPD ) as shown in powerled.jpg
HDDpins.jpg shows the connection of HDD led, the white goes to pin 3 or HD- while the red goes to pin 1 or the HDD .
I cropped these images from the manual which is also available at the gigabyte website.
Hope this gives you some ideas and workout of you. Good luck and pls post again how things turn up. Kind regards.
