If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.A power supply or system board failure has occurred. Try to isolate the problem by removing or disconnecting all cards, i.e. video, sound cards and disconnecting CD/DVD and hard drives.

An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Since you replaced the power supply, my guess is that the motherboard has a problem.
Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Had the same thing happen to me today and in my case it was a code 18 as they come...
It started while I was installing a video card adapter for a dual monitor setup. The solution - I had to simply close the side panel I had left open for testing and then reboot the server. The intrusion alarm went off.

Hi,
If this the light is solid amber in the front of the computer.Try doing the following steps

1. Disconnect the power cable from the back of the system tower. Press the power button on the tower 30 seconds.
2. Reconnect the power cable to the back of the system tower and power it back on.

If the amber light is on the monitor power button and the tower power button is off or blinking amber it could mean that it is a bad power supply.
