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.

Hi;
you should check the capacitor in the secondry side of the power supply,

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

Hi,
Does the orange LED go green when the machine is working? if so take out the system ram (memory) clean the contacts and the slots, reseat the ram and try to boot up.



Good luck.

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
