No pwer to my system until I pull the 12Volt 4 pin power connection to the Motherboard

I have an Intel BOXD945GNTL motherboard. There is no power until I pull the 12Volt 4 pin power connection from the Motherboard but I get no video and the DVD drives do not open. Is the Motherboard bad or the CPU chip? What does the 12Volt 4 pin power connector do anyway. Thanks, Rhytheman

Re: No pwer to my system until I pull the 12Volt 4 pin...

As you say,the motherboard or the cpu may be the problem, as you need to connect the 4 pin connector as this is the independent 12v power supply for the cpu and not the ZIF socket like older cpu's. You may be getting power to the board when the cpu is not connected, but when it comes to the cpu taking over because the bios has not been checked, nothing else will run, including drives. If you do not get as far as the bios showing on the screen there is a good chance that the cmos chip is damaged on the board normally either from new or because of the board being stressed from flexing when fitting components to the board which is easily done unless the motherboard is supported by something underneath when attaching parts. If the board is already fitted into the chassis of the pc, remove it and double check that it is not shorting on the chassis of your tower.

On switching on the PC, the processor fan runs for 1 second and then stops. Nothing else happens after this. I have replaced the power supply unit but the problem still persists.

Check all connections and cards to make sure that everything is secure, is your system speaker still connected? Does your graphics card require its own power (6-8 pin) check the 4 pin cable if intel.

Power led is connected wrong..need manual for

The power led on most motherboards is two pins. Flip it around. To find the manual, you need the model of the motherboard, not just the chipset ID. Do you have that? If so, you can navigate to the site and search there for your device motherboard. Then select manual.

Can not get motherboard to boot up

the things youre describing that are not controlled by the same power connectors. the 1st set that works are powered i think by the main large rectangular power connector. the stuff that's not working require more power connections. the cpu fan has a small wire that connects to a small connector on the motherboard right near the cpu. the optical drive connects to one of the the 4 pin power connectors coming from the power supply, same with the hard drive- same power connector. the front usb light is going to connect to a specific tiny 2 pin connector on the mobo, it will be labeled with tiny white letters-- try to find or download the manual. godo luck!
