Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacement from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic

SOURCE: power supply light has blinking green light

If the power box is bad, The computer will not come on. if you only get a green light, you would need to start with replaceing the power box, if you get a new one and the same thing happens, then the mother board is bad too.

Computer power supplys are modular replacement fixes. Better to replace the whole thing then try to repair.

SOURCE: Flashing Green Light on Power BESTEC Power Supply

Hi. NO, *********** board is not fried. I am not sure what the problem is but I do know how to fix it. It is usually casued by power outages (even if you have UPS supply).

1. TAKE OUT THE ELECTRICITY LEAD TO THE COMPUTER. Look inside the computer and find the bunch of wires coming from the power supply unit (the box thing at the top with the fan and all those colouted wires!).

2. Find where these wires run into a plastic connector and plug into the mother board. Unplug it.

3. Now plug the electicity lead back into the computer. The light should now stay ON.

4. Plug in the connector again... and boot up. Leave it run a while to convince it!

5. Repeat this process if it does not work first time.

This should fix your problem . It works for me when I get this problem.

SOURCE: Pwr supply not getting power to the mobo.

No fuse, but they are relatively inexpensive, about $30.00. You can have yours load tested by a reliable local tech to confirm it has given up the ghost...and they'll probably be happy to supply a new one as well...
Here's a startup troubleshooter that has more info if you're interested in self-testing...

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Dell Optiplex GX280 Power switch flashes white light rapidly system will not turn on Fans do not start


Outlet - unplug the power cable and put it on an outlet on its own Power Cord - make sure you remove the power cable from the back and plug it back in to make sure you have a good connection. things that cause this blinking light: Power Supply -open system and follow cables to make sure its connected well to each part. I/O Panel - this is where the power button is at . just open the system and follow it behind the power button.the flat cable going to the mother board , disconnect it. plug the power cable to the wall and if the system starts up then the power supply is good and the the cable that you just disconnected is bad.

If it still doesn't power up remove
memory
hard drive
dvd/cd drive
and start the system.
no luck then it is the systemboard.

Flashing Green Light on Power BESTEC Power Supply


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.

I hope this helped! Good luck!

HP Pavillion automatically restarts after shutdown


indication of a failing power supply??? I dont think so.
more like a driver is corrupt or better yet have the on board nic card set to turn on, is there a plug that has wire attached to the nic card, unplug those and see what happens.

Pc won't turn on


Hi, Are you able to test or repair some of this your self? is so use a multimeter and check the power supply,If you get no reading then remove the unit and open the cover, on the printed circut you will find a fuse either glass or ceramic. Replace this and also clean all dust from the unit replace the cover and reinstall in computer. If this fails you may need a new power supply unit. Regards mistyman
