I found something close, Frightfest's DARK HOUSE 2009. It has a young disturbed black haired girl who cuts herself on the hand. But the one I am looking for I think she cuts herself on the leg, or thigh. The decapitating automated disc and other automated traps arent there.
Plus this film is 2009 and not early 2000.
Weird thing is I watched it in 2003?
