Chosen Solution
Installed SSD recently and everything worked for a week. This morning, I was unable to power on the machine. Disassembled the machine and peeled back the EMI cover. The first LED light came on as soon as connected to the power source and both fans jittered. When the power button is pressed, the second LED came on and stayed on. However, nothing happens. The third LED light never come on. Kept holding down the power button and the second LED went off. Any advice would be greatly appreciated.
Sounds like a bad power supply. Also examine the 24 capacitors for swelling and/or corrosion.
This is an all in one desktop unit.
