Thank you but perhaps I did not word my original post correctly. Evidently I should have said, “Computer does not POST (no beep), No Video, nothing but “On power up, CPU & system fans come on and the Board Status LED "F" flashes green, "K" flashes red and "L" is solid green. The Post Code LED display shows B0.” I did find a thread that said that a DX79TO with an i7-3820 will not post due to the revision of BIOS not being 0460 or greater. Would you agree that this sounds like the trouble I am having, or is there something else you could recommend that I could do?
Hi Gary, "I'm not calling you uncle ",
I have the same CPU 3820 on DX79SI & I am 100% positive that you need at least the 0460 BIOS version for that CPU to be detected by the board.
However, the Post code B0 means "check Boot Device". So It's as Mike said:
You are using a 2TB HDD, so it will not be detected by the system. You'll have to enable UEFI in the BIOS.
From what I understood your system is not booting so you have to check your BIOS version with that specific CPU, then enable the UEFI in the BIOS.
Keep us updated
