You could probably use that 9400 with ME-2, but it's below the ME-1 minimum Geforce:
www.gpureview.com/show_cards.phpAs you can see in the side by side, Your card is only able to reach 40%, 75%, and 75% of the minimum card's performance measurements for speed.
A 9400 is just a renamed 8500, a three year old borderline level card that was already down into the business level by the time it was renamed.
I don't know what is causing your crashes, however. It ought to "try" to run with that video card, and just do so quite badly.
P. S. For any automatic criticisms of all things named "Celeron", the word back when the Celeron "D" (for dual) was still being produced, was that it was a rather "un-Celeron-like" part, roughly equal to a 2.6 GHz P4D cpu.
