|When you mentioned 2001 and "look for items", "solve problems". I instantly thought of "Myst", which is a puzzle type game where you look around for items and solve puzzles. There are many games of Myst, in 2001 Myst III Exiled came out which is one I remember playing.|
It might be one of those games so have a search around.
I also found a list of similar types of games which could help;
