Hardware Issues????????

I have a lot of ideas for possible uses of technology in the classroom, however, I have encountered a number of hardware issues this year. I have 5 computers in my classroom that have been offline for two years. Yes, two years.I have requested assistance multiple times this year, and I have been ignored by the tech coordinator in my building. It's really frustrating to work with someone with this type of attitude, but I refuse to become discouraged. Its just sad.
