Plug your pc directly to your wall outlet and see if it turns on. If it works, then the problem is your power supply. If power supply has a reset button, press it and try again. If pc does not turn on when plugged to wall outlet, then power supply for pc may be out.

My computer will not turn on we had a power cut and the computer was running at the time power didnt come back till morning now and there is a blinking green light that use to be a solid green light


The power supply is very inexpensive and can most likely be bought from any of your computer retailers, Amazon - Just make sure to confirm the right model type of power supply. BEST to have it tested before replacing it. To make sure that is the issue.. Many computer shops will test for free.

If you didn't accidentally unplug the four pin connector near the CPU, you need to replace the power supply. This is actually a fairly common occurrence with the cheap ATX power supplies being tossed into systems these days.

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 replacemnent 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

Power supply led blinks but will not power up


My gateway was powered up and I came back into the room and it was not. It would not turn on so I checked the power supply with the paper clip jump method (which is the only thing I know how to do) and the green light along with the fan turns on. While it is plugged into the pc, it blinks with no fan running. The power supply is an ATX 300-12EB3. The Gateway is 556GE. Thank you for any help I can get on this.

Power supply or motherboard problem?


Hi talissap,

The blinking light is telling you something about the PSU. First check any AC mains voltage select switches for proper setting. US should be 115. Second if you have a multimeter, you could test the PSU for voltage. Disconnect all power to all components. remove all components from the board including cpu, memory . Leave the PSU only plugged into the board. Press power. If the fan turns on then it's not the power supply. The brand power supply isn't the best, I've seen where you need to wait for 5-20 minutes for the blinking to stop, at which time it will fire up. Now, if it doesn't power up, then it's most likely the PSU.

Good Luck,

Mark

HP Mod a500n PC, flashing green ps light


Your power supply is fried. I had the same problem with my Bestec ATX 250 power supply. I fixed the problem by installing the StatTech model: ATXPOWER250. It was easy to install and works well. It is almost identical to the original but more quiet. I got it for $29 at MicroCenter.com. Also at online Newegg.com, Radioshack.com, Provantage.com, June 20,2009
