Just installed one of these cards myself. I did a little searching around and found that if you clear the CMOS, by adjusting the jumpers located on the motherboard as indicated in the manual, it will do the trick. Simply unplug the computer, move the jumper, leave it for a minute or so, then move it back to its original position and plug it in. Worked for me :)

Re: MOTHERBOARD wont boot up
Verify that when you mounted the motherboard you placed all the mounting screws in the right places one misplaced screw and the charge sent through your motherboard will be pushed out and dispersed into the case

Hello, You might have a bad motherboard and need to replace.
First, I know its a pain but disconnect and reconnect all cables verify that your not missing one of your power cables look for any connections on the board that don't have cables hooked up to it. take extra care when hooking up your power button cable. Its easy to accidentally place them in the wrong pin.
Hope This Helps
Does the fan on the power supply run? As you say the power on switch lights up and so does the motherboard, means that the power supply is working. Monitor gets power from the socket on the power supply. Try plugging it in the wall socket. Try to unplug the main power cord from power supply to the motherboard. The one that has a broad plug at the motherboard end. Replug it and they power on the PC.
Verify that the cpu is properly seated and latch is closed. Check that the power supply connector is properly installed and the power supply works. Double check your connections on the motherboard for the on/off and rest switches are correct. If you do not have the switch connector properly hooked up then you will get no response from the computer when it is pressed. Also check that the screws holding the motherboard to the case are screwed in tightly...the board uses these screws for electrical ground.
there are many things that can shut down a motherboard.
power spikes, the caps on the board, a blown diode, voltage regulators alot of people use a power strip to protect there computers which is wrong they will not prevent a spike from getting to your hardware, even tho the light comes on the board (3.3v) if you do not have 12v or 5v getting through the board theres no way to get it to go the only thing you can do is see if you can find someone who fix's the boards or upgrade to a new mobo or find a replacment on ebay or one of the other sites
it could be your power switch, veriy that it isnt the power supply by
1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply
to check case switch and board switch
1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins
if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,
if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board
Some power supplies have a microswitch that prevents a turn on while the case is open. Sometimes it's a switch on the case, or a switch linked to the mobo. You can try to defeat that. Also PSU's are made so they won't turn on unless hooked to a mobo. You will have to jump some pins to defeat that. This info is readily found in Google.
