This computer is out of warranty. The computer worked good for 2 1/2 years. Then I got a steady amber light when pressing the start button. Now when I plug in the computer I get a steady amber light. I press the start button the computer comes on for a couple seconds and then shuts down ( the fans are running). When I press the bist button in back the green light comes on the 3 seconds then turns off. I replaced the  cmos battery but that does not help. I put the ram in a different slot and that does not help. I paid $400 for the computer so it is not worth paying a lot to get it fixed. I had a BIOS update a week before I ran into this problem.
