A good amount of threads lated are named "newbie needs help" or some variant thereof. Doesn't bother me - just noticed that.
Anyway, it seems like MAME is trying to feed a resolution your monitor cannot display. You may have to adjust the options to not let MAME do that. Based on the regular MAME's ini, I change resolution from "auto" to something else the monitor can read. This is the quick and dirty way and in the future you may want to give each game it's own .ini file (again, I'm referring to regular MAME - not 32) specifying a specific resolution. There are tools to assist you instead of making hundreds of .ini files yourself of course.
