Hi Amirkal,
The Blinking Amber LED light could indicate a possible system board, power supply, or peripheral failure has occurred.
To troubleshoot:
Power off computer, leaving the computer plugged in. Press and hold the power supply test button on the rear of the power supply unit. If the LED next to the switch illuminates, the problem may be with your system board.
If the LED next to the switch does not illuminate, disconnect all internal and external peripherals, and press and hold the power supply test button. If it illuminates, there could be a problem with a peripheral.
If the LED still does not illuminate, remove the PSU connections from the system board, then press and hold the power supply button. If it illuminates, there could be a problem with the system board.
If the LED still does not illuminate, the problem is probably with the power supply.
