    Default Gigabyte Z97MX gaming 5 Bios reset problem

    Hello people, how you all going today,

    My name is Daryl, i have been a PC technician (+MCSA) for a while now and I'm looking for other expert advise/help with my problem.
    Just upgraded my rig (tax return gift) and i am having one annoying problem.I Just bought the system last Friday. Brand new motherboard, memory and CPU

    My problem is every time i cold boot the PC i get a bios error message saying my

    "Bios has been reset - Please decide how you want to continue
    Load optimized defaults then boot
    Load optimized defaults then reboot
    Enter Bios"

    So i initially thought the bios battery is dead, checked the voltage of the battery it read .2v (battery DOA). New battery installed, same message. Been like this all week. At night i shutdown windows, i switch off the PC at the wall then the next morning the bios error. My bios setting are not getting saved.

    So at the start of my day i setup the bios and it runs perfect even if i do a reboot. The problem is only once i turn off power at the wall, i lose my settings.
    The new battery i replaced is still reading 2.8V which means its still good.

    Ive tried taking everything out of the system and replacing 1 by 1.
    Upgrade the bios to version F4
    Replaced battery.

    I can only say the cmos battery holder has some cracked soldering joins or a track on the board is cut somewhere. I have contacted gigabyte tech support and im waiting for a reply but I'm open for any suggestions.

    My setup is
    I7-4790K
    H220 WATER COOLER
    Gigabyte Z97MX Gaming 5
    kingston beast 2x8gb
    3 various SSD's
    Gigabyte Odin 800w PSU
    Gigabyte 280x
    Antec 900 case



    Regards
    Daryl

    Hi and welcome to our forum.
    Yea,it's unusual that new board came with death battery.
    Can you try to clean this cracked soldering joins in battery holder ?
    Seems to me is shorted,so like Clear_CMOS..... must start setting all over again.
    If new battery is already 2.8V...very soon will be death again.

    Yes,contact your shop or GB direct.

    Edit:
    Can you check with multimer resistance of Clear_CMOS pins?

    Hello stasio,

    thanks for your quick reply.
    I tested the clr_cmos pins and got no readings at all, open circuit which right.

    That's good.....
    Also you can check in battery holder.
    Anyway Clear_CMOS pins for 10-15 sec (with battery in, unplug your power supply), maybe help.

    Ok, the battery holder read 1.08ohms at 20k,
    i tried removing the power supply and reset still no good.
    Any other ideas are greatly appreciated.
    Thanks for your time so far.

    Daryl,
