Hp desktop blinking green light won't come on

Step 1 : Turn off the system by pressing the power button for 5 - 10 sec until the power LED is off. Removed all cables including the power cable (Exclude monitor cable and KeyBoard/Mouse).

Step 2 : Press power button for 5-10 sec again to drain fela power.

Step 3 : Reconnect the power cable at the back of the tower/computer and power on the system.

**If the same problem exists, Call HP tech Support (800-474-6836) because there is a high possibility that you have a bad Motherboard or Power Supply on the system.

Your power supply is bad--you will need to replace. I suggest looking at tigerdiect for a replacement.

SOURCE: blinking amber light with green 4 light

If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.
Try, unplugging the power cable from the pc, and reinsert it, if this does not help try a differnt power outlet, if this dont help, open the computer, take the power Molex conector out of the mother board and try turning it on, if this dont help, take out the Memory modules and reseat them, if this dont work you may want to ring up dell support.

Hope this helps!

SOURCE: computer will not turn on. green light blinking

Try replacing the power supply, a blinking green light usually means the power supply is missing an output voltage. If you do that and you still get a blinking green light then the motherboard will need to be replaced.
