Update. I felt (given that it is pouring rain here today) that it was time to move this topic along.Gained access to BIOS (via F2) Entered "drive configuration' Found that SATA drives (primary and secondary) were "selected "OFF".Not knowing which of the 2 i was connected to i selected both into the "auto" mode.Saved changes and exited the BIOS.Restarted the computer.Message came up indicating "no primary SATA found."New hardware found window opened identifying correctly the SATA DVD rw drive.Next window to open was searching for drivers. Nothing really occurred after that window closed. Inserted a variety of media into the SATA DVD rw drive. All instances the little green light on the front of the drive bay illuminated for a brief period.I could hear the drive spinning up. No windows ever opened on the desktop. No audio/video players ever opened. No audio or video ever displayed.I have windows media player,realplayer.roxio version 5,musicmatch in programs on that computer. Any other info required please ask. Suggestions please. truenorth
