HP Pavilion dv 6915nr laptop not booting, all lights on steady

I saw an HP Pavilion dv6915nr laptop that was basically not booting. When it was powered on all lights stayed on on steady, no beeps, blank screen. The problem was one of the ram slots is bad. There was one 2gb stick and one 1gb stick installed. In the slot higher off the board both sticks work but the system fails to boot if either stick is placed in the slot closer to the board. The system is stable with one stick so the 2gb stick stays. The machine is running Vista 32 bit SP1.
