What video card do you have? Are you using the DX8 or DX9 renderer in MAME and MESS? (see mame/mess.ini)

It sounds like you may have defective video RAM, or, if you're lucky, it's a driver problem.
Try completely uninstalling (until your video card appears as "Standard VGA Controller" or something like that in Device Manager) and then reinstall your video card drivers.
