DOOMLancelot

I have this video problem with Dungeon Keeper 2 which can be seen here: http://i136.photobucket.com/albums/q195/DOOMLancelot/DK2problem.jpg It says I have low hard drive space, but I actually have 54.8 Gigabytes of free space. The black lines are the annoying part because they show up while playing the game also. Is there any way to fix this?

Well....I looked in the troubleshooting file about the parameters and it's still the same way.....I was planning on getting a new graphics card but there's so many other things I'd like also. So, does anyone out there know how to fix the black lines on the screen?

Ok......would it help to say I have a Silicon Integrated Systems 760 (SiS 760) graphics card!?

Come on, anyone?
