No power - LED light blinks.

check any damage on the display board and inspect the wiring

This is a system fault but unfortunately,you may have to replace either the power or motherboard depending on whether the green LED blinks continuously or completely dead

This is an easy fix so here you go nice and simple:

Problem: Your motherboard circuit has been cut.

Causes: Power disconnected during operation. Power outage or short in the surge protector.

Symptoms: Flashing green light on both motherboard and power supply. System will not power on.

Solution:

Step 1: Ensure that both the power supply and the motherboard lights are flashing green, not solid or off.
Step 2: While the power is on, disconnect the power supply from the motherboard. This connection is the largest of the connections and should be listed as the 'P1' or 'Primary' power connection.

Step 3: Wait until the green light on the motherboard stops flashing and check to ensure that the green light on the power supply is now solid. If it is not solid, disconnect the power to the power supply and wait until the light turns off completely. Then reconnect, it should be solid now.

Step 4: While the power is on, reconnect the P1 connection to the motherboard and you should now see that the light on the motherboard is solid.

Step 5: Power on your PC. The problem should not persist.

Warnings: If the power supply light remains flashing after you have restored power to it while it is disconnected from the motherboard, it may be a system failure in the power supply itself requiring replacement. Always be careful when working with an active or live power machine.

Remove the side pane to access your motherboard cables, etc. Locate the connector on your motherboard that contains the wires going from your power supply to your motherboard. It will be a large, rectangular connector with a lot of individual wires It is not a ribbon cable but should be located next to a ribbon cable connector and next to a green blinking light on your motherboard (when the power supply is plugged into the wall). Note: This green blinking light is in addition to the green blinking light on the back of the PC.

This next step is important: You have to disconnect the connector noted above from the motherboard WHILE the power suply is plugged into the wall. Wait a few seconds and plug it back in. The blinking reen light on the motherboard should now be a solid green light. The PC should now power up.

If the steps above don't work you will need to get a new power supply.

Here are some troubleshooting steps. From your description, my impression is a bad motherboard.

System cases vary when it comes to wire colors. The most common wire colors for positive are, solid blue, light blue, solid red, solid green, light green. Negative wire colors. Each led, IDE-LED, Reset, PWR-LED and PWRBTN should share a negative colored wire. Common is the solid color white but this can vary from case to case.

Good luck!

1. Remove All External Devices
2. Check the Computer's Power LED
3. If the power LED has not changed unplug the Power Cable From the Computer Disconnect All Hard Drive Power and Data Cables and power on the computer. If still no go.
4. Remove All PCI, PCI-E, and AGP Expansion Cards .
5. Remove All Memory From the Computer
6. Reseat the ATX and 12-Volt Connections . The ATX connector will be a 4 pin square connector connecting to the motherboard from the power supply and the 12-Volt Connection would be the biggest connector with a lot of colored wires.
7. If still no go.
8. Disconnect the Power Connection to the Chassis Fan
9. If the light still flashes then it could be a power supply or motherboard failure. Try a good know power supply first and if that does not fix the problem it is the motherboard. Also check the back of the tower for 4 lights lables ABCD or 1234.
Rate if useful.

Dead short on the machine causing the power supply to go into shutdown (Fold Back Protection)

Remove all of the connectors coming from the power supply (Label them so that you know here they go back to on the Motherboard and the DVD etc (Including the processor fan one)

Place all of them back one at a time starting with the main one if the led stays on then plug in another till you locate the short.

If the led dies when you plug in the main MB connector then you are in deep brown stuff

All you can do then is to remove the Ram and any other unpluggable device to see if that is the cause

I hope this helped! Good luck!
