Hey,
first of all, it's best to upgrade to the newest patch for Hardwar - version UIM 06. Here's a link to the download page: http://zedo.hardwar.org.uk/dexdown.htm it's called 'Ian Martin's UIM 6 Patch'.
Make sure to:
-under display, select one of the graphic options. If one doesn't work, try the other.
-Set resolution to that of your screen.
It's quite an awesome game, I remember playing it years ago. Still my favourite.
Also, out of curiosity, where did you manage to get your hands on Hardwar 10 years after it's release?
