Hi,
If the power button light is blinking yellow . Generally it means the problem is with the power supply and needs to be replaced . If after replacing the power supply the problem is not solved it would be the motherboard failure.

If the power light is blinking amber -
The computer is receiving electrical power, but an internal power problem might exist.

  • Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
  • Ensure that the processor power cable is securely connected to the system board.

Dell OptiPlex GX520 PC Desktop won't power on


An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Dell optiplex gx520 flashing yellow light on motherboard


According to the information you gave it seems it can still be the RAM. I've had a few PC's unable to startup due to bad memory.

Either that or the the front panel conectors are wrongly connected. Sometimes they do have a color code, but it's best to reference the manual. Can be the button . . .

If this is no help, I'd like to know more.

Here is the info straight from Dell. looks like you have an internal power issue. You will most likely need to contact Dell directly for assistance, they are pretty good about giving support even if the system is no longer covered under warranty.

If the power light is blinking amber -
The computer is receiving electrical power, but an internal power problem might exist.
  • Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
  • Ensure that the processor power cable is securely connected to the system board.

Why would the on/off button be yellow-orange instead of green when the computer is turned on?


Solid yellow-The Dell Diagnostics is running a test, or a device on the system board may be faulty or incorrectly installed

Blinking yellow- A power supply or system board failure has occurred

post again here if you need further assistance..
