A Bronx man went berserk and slashed his 9- and 17-year-old stepsons’ necks during an argument over a home computer Friday night, police sources said.

The violence erupted about 7:30 p.m., when the stepdad pulled a knife inside the family’s apartment on Ward Avenue in Soundview.

“Apparently the stepdad wanted to use the computer, but the boys were using it,” a source said.

The two boys miraculously survived the savage attack with only minor wounds, and were taken to Jacobi Hospital in stable condition, according to authorities.

Sources say the crazed stepdad ran off into the chilly November night without any shoes or shirt before cops arrived.
