Nabokov (20-3-3) became the second NHL goalie to post 20 wins. He fell just short of his third shutout of the season.
"It will get even harder because we're facing desperate teams that are hungry for points," Nabokov said. "We have to match it every night. It'll be harder and harder from now on."
The Stars went on the power play when Dan Boyle was called for a penalty with 3:52 left, but couldn't get a shot on net with the man advantage.

"We're looking for playoff positioning," Cheechoo said. "We're not just going to be satisfied to make the playoffs. We want to secure home ice advantage."
Cheechoo's sixth goal of the season gave San Jose a 1-0 lead at 15:10 of the first. Cheechoo deflected Boyle's hard shot past Turco.
The Sharks extended their lead when Michalek, who slipped while taking a pass in the slot, scored from his knees at 3:55 of the third.
But Nabokov and the Sharks fended off the Stars in that 5-on-3 chance. Nabokov made a kick save on Mike Modano's shot from the right circle seconds into the power play.
Dallas, who had scored 24 goals in its past five games, was 0-for-6 on the power play.
"We controlled play and had some good chances," Stars coach Dave Tippett said. "If we play like that, we'll get our fair share of opportunities and win our fair share of games."
