I am trying the demo version of mach for the first time and seem to be having trouble. When i click on the short cut icon the computer restarts. I have deleted the mach and reinstalled it and the start up has nothing running. the os is windows 2000 professional.

Try doing the optimisation, you should find the directions on the downloads page. If at all possible it might be best to start with a clean install of your OS.
