Yellow Amber light on Dell Optiplex 390 not booting or display what to do?
A steady or Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. 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.

Flashing amber light on power button
Correct, the only step you can try is to reseat the memory chips. it should fix the problem. the power supply seems to be good here, as well as bad.
confused?
why good? becasue it is supplying the power to the computer and the only reason you see the light on the tower.
why bad? becasue the power supplied is not enough for the computer to start.
Now, the power is going to the motherboard, if you see any light on the motherboard the power supply is okay and then it became the duty of the motherboard to forward the power to all the components. so reseating the cables on the motherboard should fix the problem, most probably memory can cause such problems. so keep your fingures crossed and then restart the computer after you done resseating the memory and other cables, if it still doesnot work. then you may need to use the hit and trial method to find out if its a power supply or motherboard.
we normally replace both the parts in such cases.
all the best.
