Try running the campaign map at a higher resolution, djaked, MTW campaigns can be extremely touchy (I have intel graphics too) if the map is not set to 1024x768.

There is a thread around here somewhere, which was pertinent to my problem, which gave specifications for a particular Intel graphics chip (Which just happened to be my one), and which older driver to download for it and where.

If you also need to reload an older driver (Newer driver perhaps?) in which case we should start researching just what sort of Intel graphics you have.
