I had my Optiplex GX520 at work shut down abruptly every time I turned it on it in the morning. This would always happen within the first 30 minutes. I would then get the flashing amber light. After starting the PC again, it would stay on all day (over 8 hours) without shutting down again. I found that the power supply was over-heating.

Two things need to be done. First, in order to get the amber light to stop flashing, un-plug the computer from the wall for 30 seconds then plug it back in. OR hold down the power button for 10 seconds or so. The light should stop flashing. Then press the power button again and the PC should start.

But why did it abruptly shut down in the first place? The power supply has a fan-speed-control circuit in it to keep it running slow and quiet when the power supply is cool. It gives the power supply lower voltage when the power supply is cold and higher voltage as the power supply gets warmer. This circuit either is not working correctly or the fan getting sticky over the years and needing more voltage to get it moving when it is cold. I found that the fan was not starting at all and causing the power supply to over-heat.


To keep the fan moving at full speed, I cut the wire to it and wired it to the +12v output directly. Not the fan goes at full speed all the time. And yes, it is nosier. But at work it doesn’t matter.

The best solution would be to just get another power supply from Dell if possible. Or buy a +12v, 70mm fan from Digi-Key and replace the original.

Do a power drain-take off the power cord from the back of pc and hold the supply button for 60 sec while pc is off...check..
Remove any internal component that was recently added, such as video card, memory, CD, DVD, and hard drives. An added device may take more power than the power supply is rated for. If the problem goes away when the component is removed, the only option is to upgrade the power supply to power supply with a higher wattage rating...check..

Power button if flashing orange and nothing else works


It's likely that your power supply has started to go out. There are several different leads with varying voltages & amps. If your computer is getting enough power to make a light flash yellow or orange then this often means that there is something wrong with one or more of the voltages from the power supply. Sometimes it means that something is wrong with your motherboard. Like: burned out capacitors, resistors, & etc.

The power light keeps flashing orange when trying to switch my pc on i only get an orange flashing light no other life in it whatsoever........


It means to say that it is not getting enough power on the computer, check the power cable at the back of the tower and make sure the power cable is connected tightly. You can try taking it out and then putting it back in again to make sure it is connected firmly.
