Step 1 : Turn off the system by pressing the power button for 5 - 10 sec until the power LED is off. Removed all cables including the power cable (Exclude monitor cable and KeyBoard/Mouse).
Step 2 : Press power button for 5-10 sec again to drain fela power.
Step 3 : Reconnect the power cable at the back of the tower/computer and power on the system.
**If the same problem exists, Call HP tech Support (800-474-6836) because there is a high possibility that you have a bad Motherboard or Power Supply on the system.

just for giggles, if you open the tower and look closely at the bottom right side of your motherboard there should be wires there. the wires themselves shouls be labelled like led light, reset and so forth, now if you look at the motherboard were these are located there should be labels there for each wire. make sure they are all connected and didnt come off for the sake of coming off because they only slide on, make sure everything is in the right place coming from the power button of the front of the tower.
i had the same problem and the main power slipped off somehow, and thats all it was, just the one wire
hope it helps you

It can be the problem voltage variation. The mother board might have some problem. Please check the motherboard for any burnt parts. If there are changing is the only option.
