GIGABYTE GA-990FXA-UD3 Bios Updated: Screen Black, Flashing Underscore

I just built my first computer. I've had it running for about 2 weeks. I just updated the Bios via @Bios for the third time just now and I get a black screen with a flashing underscore at the top left.

The first two updates went fine. Don't know what's up with this update today.

There doesn't seem to be any power going to my USB mouse nor USB keyboard.

I'm new to this so I'm not sure what to do. I've tried to search about this problem and some suggestions were to use only 1 RAM stick. Take out the MB battery.

MB: GIGABYTE GA-990FXA-UD3
OS: Windows 7 64-bit
GC: VGA SAPPHIRE HD6970 2G
CPU: AMD|8-CORE FX-8320 3.5G
RAM: (2) 8G | GEIL GEV316GB 1866
BOOT DRIVE: SSD 128G|TOSHIBA HDTS212XZSTA
STORAGE DRIVES: (2) HDD 3T|TOSHIBA PH3300U-1I72 R

Thanks.

    Thanks.

    Did you try removing the Battery? (Resets CMOS)
    Can you access Setup/BIOS?
  2. Okay, I just took out the MB battery. Same deal.

    Then I took out 1 RAM stick. Same deal.

    Then I took out the battery, put back the RAM stick. Same deal, but my mouse was getting power. Not my keyboard.

    I plugged my keyboard into a different port and it got power when I turned on the computer.

    I got into the BIOS settings.

    Now the "Starting Windows" splash screen takes 4 times as long to get to my password screen, but at least it runs now.

    I'm guessing it was the latest Bios Update.

    Is updating to the latest Bios always a good idea? I don't want to try again because of what happened.
  3. Okay. Now I'm concerned.

    I went directly to the Gigabyte site to look at their drivers for my MB. Listed are Versions F1 and F2. After I removed the battery and got my system running again, I saw that F2 was the version I had after supposedly resetting the Bios. The F2 version is also dated prior to my purchase by a month.

    So I'm wondering, what exactly updated via @Bios the last three times I used it?

    ??? The latest BIOS listed is F10A...
  5. What revision is your Mobo?
    Speccy will reveal all....

  6. Have you d'loaded your Mobo Manual
    http://download.gigabyte.us/FileList/Manual/mb_manual_ga-990fxa-ud3_e.pdf
    See P54, recommend set default for BIOS etc.

    On their website, when I go to my product page, the latest Version listed is F2:

    http://www.gigabyte.com/products/product-page.aspx?pid=4672&dl=#bios

    Is there another page on their site with more updated versions?

    Page 54 states "Always load the Optimized defaults after updating the BIOS or after clearing the CMOS values"

    But what if you can't even get to the BIOS after updating like me when all I got was a black screen and flashing underscore?

    I see that F10A is for rev 1.0 and 1.1.

    Rev 4.0 only goes up to F2

    Yep, came to the same conclusion. In theory it should always be able to display the BIOS! Also recommends saving a 'working' BIOS in case of problems.
    You could always try Qflash, at least you can do that by d'loading the BIOS on another machine to a USB device. (Provided the 'End' Key is recognised!)
  12. Any progress?
