Its a MSI CUBA MS-7301, its an OEM motherboard for a Packard Bell Imedia 2470, so there is no support for it on the MSI website.http://support.packardbell.com/uk/item/index.php?i=spec_cuba&ppn=PB34338701
from the supported CPU list i would have presumed the E7400 would have been supported. I have socket LGA775, and the MB supports a 1066 FSB.
I've flashed to the latest bios available version 3.16, http://support.packardbell.com/uk/item/index.php?i=6998840600&ppn=PB34338701http://support.packardbell.com/uk/item/index.php?i=instr_bios_cuba&ppn=PB34338701
The processor had been bought from e-bay apparently pulled from a working system, im not sure whether its a true compatability problem or a dud processor.
When i try to boot with the E7400 the PC powers up, but does not boot, no system beeps.
I need advice as to whether i've wasted money on a dud, before i try to buy another E7400 or similar.
