Narrative:

I was pilot not flying and the first officer was pilot flying. Climbing through 8;300 feet the first officer lost all display screens. The #2 IRS fault light illuminated. The aircraft started to make a 90-degree turn to the right off course. ATC told us to turn to a heading of 270 and descend to 7;000 feet. Immediately I started flying the plane and informed ATC we had lost our navaids. They gave us a heading and altitude to fly. We started troubleshooting the problem and running checklists. We had no autopilots and the navigation radios were not giving us correct information. We informed ATC that we would require vectors back to land. The landing was uneventful and we taxied to the gate where maintenance met the aircraft. They replaced the #2 adiru and we continued to our destination.
