Mainboard Intel DZ77BH-55K stops booting with SSD connected after working for some years
BIOS Version BHZ7710H.86A.0100.2013.0517.0942 - 17/05/2013
I bought this board November 2012 and connected a SSD OCZ Vertex 2 SATA II as a boot device.
In October 2013, nearly a year later, it wouldn't boot anymore, without permitting access to the BIOS.
So I replaced the OCZ-SSD 120GB with a new model Samsung E840 250GB.
Four days ago, after nearly 3 years working properly, the same issue occured again - the mainboard didn't boot with the SSD attached and the BIOS was not accessible, the mainboard LED showing the POST code E6. I didn't manipulate anything in the BIOS near this point of time.
Booting only was possible with the SSD removed and another SATA HDD as a boot device connected.
Interestingly tests with both SSDs on 2 other computers (an Abit-IP35Pro 2008 and a halfway new Medion-Laptop) were showing them working and booting properly.
Aside this problem the board also won't boot with connected external USB devices. To persuade the board into booting I have to remove ALL (seven) external USB devices. For this reason I instructed the BIOS to boot the USB devices after booting into the OS.
Now it asks for the boot device because it doesn't find it by itself, but also the POST shows a way into the BIOS by prompting F2, and F10 for the bootloader, but the the USB keyboard too is not connected at this time, so I cannot answer the BIOS' questions. Thank Heaven I found a grime covered ancient PS/2 keyboard in some corner, so I could resolve the problem for the moment. Permanently though I would prefer a more convenient method to boot the system.
I beg to excuse my somewhat clumsy English, asking for your help:
First, is there some workaround to reintegrate of my SSD into the system as a boot device, and second, is there a way to circumvent the booting of the external USB devices without disabling the USB keyboard/mouse at the same time?
Thanks in advance.
