SOURCE: No power, power supply & motherboard green light blinking

I had the same exact problem for the same exact reason. Plug the power cable into the back. Open up the side of the case and unplug all the wires that the power supply plugs into. The motherboard, harddrive, cd & dvd drives, everything. wait about 10 minutes and plug them back in, plugging the BIG cable that connects to the motherboard back in LAST. This will make the light go from blinking to solid. I think it is a safety? to protect the motherboard from damage.

SOURCE: psu blinking green light, no power

I read all the solutions, followed the manufacturers instructions exactly, replaced the cmos battery and nothing solved the problem (blinking light on PSU after a power failure and no startup at all). I had ascertained that the PSU was intact by disconnecting all the PSU connections to drives and motherboard at which time the PSU LED stopped blinking and was constantly on.
Just before throwing my computer away I decided to follow the instructions listed by "guest" to unplug the power to the motherboard and then with the power supply back on to plug the cables back into the motherboard. No only did sparks not fly, but it started up and ran perfectly! Many thanks to "guest."

When the computer is plugged there is a fast blinking green light and will not turn on


A fast blinking green light means the power supply is bad and will have to be replaced. Make sure you replace it with a least the same wattage supply that is in it now.
Hope this helps.

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.

Bestec ATX-250-12Z Rev.C Green LD starts to blink


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

Not booting, blinking light


4 blinks, 1 second apart is a power supply overload. Have the power supply replaced if you haven't added any additional hardware lately. But also make sure your hard drive isn't bad and pulling an overload of power. it's rare, but I have seem that happen on some western digital hard drives.
