There's an edit button/option, when you're typing a post. Please, don't double post, just add what you wanted to say in the prior post, unless someone else has posted after you.
As for free HDD space...Err...It should show up on your screen when you enter "my computer", right next/under your partition's name (C:/ ; D:/ etc.).
Just in case you're wondering, RAM amount could be viewed by right clicking on "my computer" -> "properties"...(If you're using Windows, that is)
But if Chrome crashes your PC, then I don't really see how you manage to run MaB, hence any mod.
I think you should visit The Apothecary, http://forums.taleworlds.com/index.php/board,6.0.html , as this is not a technical support thread, but I really doubt that would solve your problems either.
Either way, your problem seems to be more of a hardware one, rather than a problem with the mod, which defines this little discussion as spam (which means, this is not the place to ask about all that jazz).
Anyway, good luck.
