    OK ZCommander,

    I saw the You Tube and here is how I would start (the whole article is found at
    http://forums.tweaktown.com/f69/bios...h-guide-27576/


    Clearing the CMOS

    CMOS is a Acronym for "Complementary Metal Oxide Semiconductor"

    Clearing the CMOS will erase the settings stored in the CMOS. It does not remove or change the BIOS itself, it only clears the user defined settings within the CMOS.

    This is a very useful thing to do, that everyone needs to know how to properly use . It can often help if you are having overclock issues, if your PC will not stop the booting cycle, Or some people choose to clear CMOS when they plan to flash. All of the above are normal times for you to use this function

    When you clear the CMOS you will often likely see the error message "CMOS Checksum Error" on the next reboot. Do not worry this is a normal thing, please enter BIOS at this stage and Load Optimized Defaults, set your DDR2 voltatge and reboot again to the BIOS. The error will be gone after that.

    Incase anyone is confused by that error message statement above, the Corrupt BootBlock/Scanning for BootBlock Error is the one you do not wish to see, the checksum error is fine and will be gone on a reboot or with one setting change in the BIOS as the board will update the DMI pool to match the CMOS and the checksums will then be matched

    First thing to do is to shut down your System, and let it rest for 30 seconds to a minute.

    Then it is wise to unplug the Power Supply from the wall. Open your case and find the "Clear CMOS" jumpers. It is a 2-pin jumper normally located just under the or between the PCI-E slots in P35 boards and under the last PCI-R Slot in P45 boards. Once you have found these jumper pins you will need to get a Hard Drive or Optical Jumper (The same type you used to use on IDE Drives) and place this jumper on the "Clear CMOS" pins. Then press and hold the Case Power on switch for a minute.

    Boards with A Clear CMOS button you may also Press and hold this for a minute as well after you do the power button. Sometimes this Clear CMOS button alone will work, other times it will not. So this FULL method is just to BE SURE it gets cleared for those users who have issues with other methods

    You may also want to remove the CMOS battery. This is optional and not Always necessary, but you may want to try it if you are having issues getting the CMOS Cleared.

    Below is a Example from P45-DS4P & P35-DS3R Gigabyte Manuals



    Now let the computer rest with this jumper on for 10-20 Minutes, this will ensure that the battery gets drained, and the CMOS is cleared. Some people will tell you it will only take a few seconds or a minute or two, but I find that to be false and it may indeed lead to a corrupt BootBlock and or a Bricked motherboard.

    So best to not try to cut corners when it comes to Clearing the CMOS, wait the full 20 Minutes

    When the 20 minutes is up, remove the jumper from the "Clear CMOS" pins, put the battery back in if you removed it, and close your case up. Plug the Power Supply back into the wall and restart the system. Then please follow above advice and Load Optimized Defaults, set DDR2 Voltages and Reboot.

    Lsdmeasap, thank you for the reply.
    I'm currently on F6i, Loaded the optimized BIOS settings and still no luck, I found a faster way to boot my computer when it fails to boot. it's by removing the ATX power cable and wait for 10 sec. then plug it again ! It will boot after that.

    I had this problem withh All the BIOS ver. that I applied, F3,F4j, F4, F5, F6a, F6g, F6h F6i.

    Damn I thought I reached something there, removing the ATX power plug doesn't make booting easier at all.

    I figured what the problem is….. I sent the motherboard for the store to check it out by their technicians which after 3 days informed me that the motherboard is working fine, today I went to the store to see by my own eyes, and while I was there I figured out what was wrong……………….. it is the USB port 1 on the motherboard, if any USB based storage device is connected to that port during a cold boot, the motherboard will fail to boot unless clear the CMOS and remove power out of PSU!!!!!

    WTF, never experienced something like that !
    While I was at the store too the technician asked me to help him with another PC LOL which I did, I should receive a new Motherboards tonight by Gods welling!

    what PSU you are using? I used Antec TPN 750W b4, i have the same problem as you and the dealer told me the PSU doesn't fit for the gigabyte motherboard. I replaced the PSU boot up fine
