The same problem with my HP. The Power Supply is bad I tested it with another power supply and it works fine. The power supply is the part with the power plug in the back. Where the green light flickers. It takes 4 screws to unscrew. Do it with the power off/disconnected. The Unplug all your devices and the Mother board plug(s) maybe 2 connections on motherboard. Also if you have black SATA connections you need to buy the right ATX power supply with serial ata for the hard drive. You can also buy a tester from newegg for around 12 dollars.

    PS also make sure its set to 120volts for US. not 240volts Industrial power. If the red switch is set to 240 the machine wont boot.

Green light behind motherboard blinking when power is connected


That is an indication that there is power to the motherboard. It normal but does not mean all is well with the PC. If your PC works fine, then there is nothing to worry.
