I have now bricked two DZ68DB motherboards trying to upgrade them from Bios 032 to 043.
How is this possible? ... just follow the instructions provided by Intel.
Sorry to sound bitter but having just received a replacement DZ68DB and hoping again to be able to load the latest Bios on it I failed a second time. I thought my first attempt was a genuine failure in the process so when I received my replacement board I again tried the F7 method, followed the instructions to the letter and got the exact same result even after the 'Successfully Updated Bios' message appeared on the screen just before it rebooted (see the picture below, I didn't photograph the final message but all results were good).
The system powers up but there is no actual start, even at the most basic level. There seems to be no power to the USB ports, evident by no lights on my USB keyboard, and although the fans plugged into the motherboard work they run at full speed without any control by the system.
In my attempts at restoring it I followed the recommended USB recovery procedure but it fails because the system seems to simply stop as soon as power is applied. There is no progress to the point where any media can be accessed even with the Bios configuration jumper removed.
There is no physical damage to the board (I just got it!), it operated normally (on Bios 032) until the Bios update was attempted. There are no failure beeps or other indications on start up.
I am simply amazed by this, how can a Bios released to provide improvements kill a system so completely?
Other users on this forum have mentioned they had success with this upgrade, some transitioned from 032 to 040 first then to 042 and 043. Maybe this is a factor, who knows ... I have found this whole process very disheartening, one month on from my upgrade attempt and I'm still without a usable system. Intel processors are fantastic, motherboards it seems not so much (in my experience).
Now it seems I'm faced with another warranty claim unless I can recover this situation somehow, I would appreciate any suggestions.
Some details :
- The only external connections are power supply, monitor and USB keyboard.
- I have two Ripjaw 4GB memory sticks (F3-10666CL9D) and an i5-2500K CPU installed.
- I removed one of the memory sticks to see if this made a difference but no change.
- I have yet to try another power supply, might do this just to be sure.
