    Default BIOS Pause After PSU Shutoff - Normal??

    If I just shut my system down and restart later, I get a normal POST beep, the Gigabyte splash screen, and then the system boots Vista...all very normal. However, if I completely remove the system from power, like unplugging the PSU, and then connect things back up, when I power on, the machine comes on, then goes quiet for a second or two, then spins up again and boots as normal. This is the kind of behavior you would expect if you'd made some BIOS changes, but all I'm doing is removing and reconnecting the power cord. Is this pause and restart of BIOS normal under these conditions?

    It may just be the DMI recharging and getting your CMOS settings again like if the battery got drained or something? How long of a unplug/replug are we talking here?

    I Am not sure though really.

    I would think it is ok though for two reasons. One you didn't say your settings were reverted to default, and two you dont unplug your System daily anyway...... So you would likely not see that unless you were messing around as you have been!

    J/K

    Na, Never heard of that unless settings were incorrect. But that description normally would be applied to a power on, not a unplug/replug of the power cord. Most people do not do that so I would never hear about it.

    Well, the background explanation here is that I have been working on this new system for my daughter, so I just pull my case out, put hers in the same spot and plug in all the cables, etc. When I need to use my system, I just pull the test computer out and plug my system in. Very easy and convenient...however, it does require that I unplug my system from the power cord, no?
    Generally, it could be a few hours before I plug my system back in again. I have noticed this double BIOS boot every time. But normal power-off and on doesn't do it. So I've gone into BIOS to check the settings, and they all seem exactly the same! (As you know, I am intimately familiar with every damn setting by now...) It claims to achieve "update success" when it does the double boot, but the settings do not change.
    Ok, one more bizarre and unexplainable quirk about this motherboard. I am totally over all the "fun" of fiddling with motherboards....

    Probably also the PSU is culprit of that boot behavior. Do you have another different one, just to clarify?

    Update success means your settings have been applied. So it is likely what I said before about since it has the power removed, and the cord for so long the cmos is cleared from being without power for so long and has to reprogram itself is all.

    Don't you have a PSU for each system yet? If so you should leave hers plugged in and you wont see this issue

    But I do think that is all it is, without power or a PSU that has stored power the CMOS and DMI pool is cleared and must be updated after power is restored
