Ok, in that trouble shooting, did you attempt a bios recovery?
I am the expert Al was referring to. Sorry I wasn't online last night to help you, but I was busy with my family.
I will attempt to walk you through the process. Follow these instructions; do everything I tell you, even if you have (or think you have) done so already...
- On another Windows-based PC (not Linux!), reformat a USB 2.0 (not USB 3.0!) flash disk using the FAT32 file system.
- Download file BC0042.BIO (from here: Download BIOS Update [BCZ6810H.86A]) and place it in the root folder of this USB 2.0 flash disk.
- Properly eject the flash disk from the PC (i.e. open Windows Explorer, right-click on the icon for this flash disk and then choose Eject).
- Power off the DZ68BC system and remove A/C power (i.e. unplug A/C power cord from system's power supply).
- Open the system.
- Remove the CR2032 battery from the socket on the board.
- Wait 15 minutes.
- Insert the CR2032 battery back into the socket on the board.
- Remove the jumper from the BIOS Configuration header on the board. With the rear of the machine closest to you, the header will be found near the right-hand edge of the board just above the (blue) Front Panel USB 3.0 connector. The jumper will be yellow and this should be the only yellow jumper you see on the board.
- Insert the USB 2.0 flash disk into one of the (black) USB 2.0 ports on the back panel of the board. Do not use (blue) USB 3.0 ports. Do not front panel USB ports (regardless of type).
- Plug the A/C power cable back into the system and press the power button. The PC should start the BIOS recovery process. An on-screen display of its progress will appear. Wait for it to say that it is done.
- If you see no display of the progress of the recovery process, wait at least 15 minutes (just in case the process is proceeding without display).
- Power off the system and remove the A/C power cord.
- Restore the jumper to pins 1-2 of the BIOS configuration header.
- Power on the system.
- If the BIOS proceeds through POST, hit F2 to enter BIOS Setup. If it does not POST, you can skip remaining steps.
- In BIOS Setup, press F9 key followed by 'Y' key to reset the BIOS Configuration.
- From the main BIOS Setup screen, scroll down to the "Additional System Information" entry and press the Enter key. Scroll down to the bottom of the display and verify that the Management Engine firmware number is not blank and not 0.0.0.0. If it is blank or displays as 0.0.0.0, you can skip the remaining steps.
- Press the ESC key to leave this scene.
- Scroll down and properly set the date and time.
- Work your way through the other configuration scenes and make any other changes to the BIOS Configuration that are absolutely necessary in order for you to boot (i.e. boot order, etc.).
- Press the F10 key followed by the 'Y' key to save the BIOS configuration and exit BIOS Setup.
- You should be able to boot to Windows now. If you see any messages displayed by the Express BIOS Update program, you can ignore them.
If you hit one of the "skip the remaining steps" points, what you should do it remove your video card, plug one of your monitors into a video connector on the back of the board and then start from the beginning of the process again. If this too doesn't work, well, it means that you have likely bricked the BIOS permanently (why, I cannot say from here) and you will need to replace the board (probably a good time to upgrade to something newer).
Hope this helps; let me know...
as you told me that my mobo is bricked therefore I bought a new one but that is of different chipset also different company actually its a cheap motherboard of $60 but as i booted into the system it already had my previous setting and also the os was same i didn't had to install anything and on logging in . It said intel express bios update was unsuccessful. for my previous bricked motherboard do I need to install everything again or can I work like this only? so can I do anything about my motherboard ?
please reply sir
There is no way to recover the board via changing the BIOS flash IC as Intel does not provide the BIOS in an unsecured form and this would be necessary to use a flash programmer. You also cannot copy the flash IC from another DX68BC board. This is because your board's branding - serial number, UUID, MAC Address, etc. - are also stored in the flash IC and would be wiped out by the programming operation. As the same time, the branding of the board you copied from would be copied to your board and this would be shared (hint: shared MAC Address is a bad thing). Now, I have the ability to recover this board properly (provided there is no physical problem with the board), but the cost of shipping it to me and back again would be far higher than purchasing a replacement board.
Bottom line, you've done the only thing that you could, namely replace the board.
Now, as I said earlier, you can just ignore the messages from the Express BIOS Update program. What you do need to worry about, however, is any differences in the features of the new motherboard. There might be, for example, differences in the LAN hardware used on the board (all Intel boards utilized Intel LAN silicon, while many 3rd-party boards utilize cheap silicon from RealTek and other providers). Bottom line, you should install all of the drivers that came with the new board. You should also go to the support site for this board and download and install the latest BIOS release and and newer driver packages that you find there.
Enjoy your new board,
