    If I waited for two to three hours for the any voltage to drop to zero on any motherboard I would never have a job working on computers. Two or three seconds is really all that is neccesary for the volatge holding up the cmos to decay below the threshold that would hold settings. Besides, since, technically Bios settings are set in flash ram now, it is moot. There is no magic involved; just a whole bunch of things that go on that can cause detection issues. Troubleshooting must be systematic, but magic doesn't help.

    So judging by your less than vague innuendo directed at me in your reply I'll assume the closest you get working on computers is sweeping the floors at E-Machines.

    In the future if all you have to contribute is vitriol please find it within yourself to stay away from the keyboard and itch something else instead.

    When Instant Flash was started, did it list the 2.70 UEFI on the screen? You then must click on it and sit back and watch it finish. Then it should automatically restart, or at least prompt you to press enter to restart.

    Did you do that? Or what happened?

    Hi parsec,

    Yes, the UEFI 2.70 was listed on the screen. I clicked on it and then all of the options in the Advanced Options UEFI screen just disappeared. When I click on the other UEFI screens they display as would be expected. The computer did not restart or offer up any other choices. I just left it running and it has been going for about five hours now.

    OK - I finally shut down the computer after my attempt at flashing the UEFI. I restarted the computer, went back into the UEFI and it still lists version 2.50.

    When I try to update the UEFI I go into Instant Flash, click on it and it brings up a box that lists the BIOS "\Z77EXT42.70" in the top half of the box with two buttons below. One of the buttons says "Configuration" and the other says "Refresh Device." Pressing "Configuration" takes me back into the Advanced Options UEFI screen. What does "Refresh Device" do? Does this update the UEFI or just look for another UEFI update on a different device? Do I just click on the "\Z77EXT42.70" to update the UEFI? Thanks.

    Yeah, you never updated your BIOS.

    Yes, you just click on the Z77EXT42.70 line and then sit back and watch it complete.

    Configuration does nothing you need to do. Refresh allows you to connect another flash drive with the BIOS file if you put in the wrong one.

    Just click the BIOS file entry, and let it run. Takes a few minutes. When complete it will prompt you to press Enter, or will restart on its own, but it MUST restart! But do the restart from the Instant Flash screen, don't press the power or reset button on the PC.

    When the PC restarts, you must check the BIOS settings, in case they change to defaults, so get into it before the PC boots. You will likely need to at least set the boot drive to your OS drive. Sometimes all the settings are just as they were before flashing, but check anyway.

    Wow! On the fourth try the UEFI update finally worked. I read somewhere else that the type of USB stick or external hard drive can make a difference. My previous, unsuccessful UEFI updates were attempted with either a 64GB or 32GB thumb drive. This time I used a 16GB thumb drive and it worked.

    Another good thing is that after the UEFI update I tried the XFX and MSI vid cards. The XFX (my preferred card) did not work, but the MSI card did work. The MSI card was detected in the UEFI System Browser and also shows up in Windows Device Manager. All I need to do is install the driver for the MSI video card.

    Based on all of this, it seems to me that the XFX video card is bad. The motherboard is not the problem in this instance. Please let me know if you agree. I opened up a support ticket with XFX and I plan to return the XFX card for a replacement.

    Thanks for your help with this.

    In theory, you are correct.
    In practice, you are wrong.
    I've seen many cases in the forum where it took 20 minutes, several hours, and sometimes up to 12 or 24 for the CMOS clear to be effective.
    One time my P35 lost its overclock and I was unable to overclock even using minimal bios changes. My normal quick CMOS clear procedure didn't help but I succeeded after unplugging the psu cable from the back of the psu, removing the mobo battery and jumpering the CMOS_clear pins for 10 minutes.

    Yep, I had a board like that too, it wouldn't clear the CMOS unless you left the jumper in the clear position for hours. I think the problem was a bad battery on the board. Sounds strange but when I replaced the battery, the problem disappeared.
