Having problems with your HP Pavilion a815n (PS512AA) PC Desktop ?
Tower will not turn on .
\015 Also the green light on the back of the tower is flashing.\015
My first guess is to replace the power supply. These are fairly cheap and easy to replace. Unplug your computer. Just open the side of the computer (often the left facing you). The power supply is on the top which is plugged in. Remove the plug and locate 2 - 4 screws that hold it in place. Disconnect the main from the motherboard (remember where this goes for later). Install the new one and reconnect power. This is the most likely reason. If that fails, the motherboard may be dead. The green light flashing indicates that the internet is ready but has no power.
If you have a dail up modem pull it out and then try to start the pc again.
