    I'm assuming you have the case positioned close by and are using the cases Power button(and wiring) to turn on the computer while it's on the MB's box?

    If so, try using the cases Reset button(and wiring) instead. I only have the online manual available, on page 21 is the desc./layout for the "System Panel Header". Top row, from the left, pins 3(PWRBTN#) and 4(GND). Connect the cases Reset button wiring to these two and if there's a red or denoted + wire put it on the PWRBTN#, with the remaining wire on pin 4(GND). DO NOT HAVE ANY OTHER WIRING CONNECTED TO THE SYSTEM PANEL HEADER, ONLY THE RESET WHEN YOU TRY THIS. I WANT TO RULE OUT ANY OTHE MISPLACED WIRING THAT MAY BE CAUSING THIS, YOUR, PROBLEM.

    I had all the wires off except the cpu fan. Tried that and I got something. the network port started flashing ans the PSU fan looked like it was trying to rev up. Plugged the fan backin and powered back up with the new results again. Oh and by "powering up" I mean turning on the PSU, nothing happens when I press the power button.

    You can try to start the board without the power switch in your case. You know where the two cables from the case switch connect to the header on the board, right? They are labeled on the board too.

    Remove the case's power button wires from the two pins on that header. With the PSU turned on, take a small screwdriver and VERY CAREFULLY short/connect the two pins ONLY that are for the case's power button. Just touch both pins at the same time for about a second with the screwdriver. That should cause the board to start.

    Well, I went to go go try this and when i turned on the PSU, it's fan started up, so did the CPU fan, and the network port started to flash. When I touched the two pins nothing extra happened. With nothing else connected to the mobo, what results am I looking for to let me know it's started?

    I think you misunderstood me there. The point was to use your cases Reset button as your "new' temporary Power button. When I said "DO NOT HAVE ANY OTHER WIRING CONNECTED TO THE SYSTEM PANEL HEADER, ONLY THE RESET WHEN YOU TRY THIS." I said the System Panel Header, not the complete and total motherboard to be wire free. On the System Panel Header only the cases Reset wiring, and that was to be connected as explained to be used here as a test to power on the computer.

    Sounds like the board started if all the fans started running. If your monitor and keyboard was connected you could have pressed the Del key and start the BIOS interface. Then you could have checked CPU and mobo temps, etc.

    Nothing like mixing multiple partially related suggestions, but it sounds like the case's power switch might not be working.

    That's exactly what I'm thinking in having him hook the cases Reset button/switch up and test IT starting the board, bypassing the cases Power buttom/switch on the chance it's bad.
    #1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.
    ____If you are overclocking, underclocking, or undervolting any parts, informing us of this and their values would prove beneficial in helping you.

    #2 - G.Skill RAM Configurator for your boardSamsung Memory for your boardLatest AMD Chipset Drivers/WindowsLatest AMD Graphics Drivers/WindowsLatest Intel Drivers

    #3 - Please use the eXtreme Outer Vision Power Supply Calculator found HERE to determine if it might be your PSU at issue.
    ____Consider your PSU to be the foundation from which all else is built upon. Anything built upon a weak foundation is poorly built.

    I went ahead and hooked up my monitor, mouse, and KB, and tried again. and it's got to be the case's power switch.

    Thanks again to -wardog-, parsec, and profJim for all your help!
