Don't keep hitting it. It would seem to be a loose connection. You will cause damage.
Unplug from mains electric
Press the power button for 30 seconds to discharge static from pc.
Take tower case off and touch part of the metal casing to discharge static from yourself.
Now carefully check all the connections of the little wires to motherboard, especially the connection from the front power light.
Check both ends of each wire.
Make sure they are properly and securely on their connectors by gently pushing on them.
Check all other cable connections in the same way.
Put casing back on pc and plug in and switch pc on.
I had a similar problem and it turned out to be noise on the 'power on' wire.
Here is what used to happen: my computer would not start properly, almost every time. It would start for a few seconds and then shut itself down while the power LED kept blinking. I had to go through a ritual of disconnecting it from the mains, waiting for LED to turn off and try again. Finally, I would succeed after so many attempts.
I had recently 'oraganized' the cables inside, it turns out that I knit motherboard wires including those that connect to the reset and power button with a 12V power cable. This was causing interference on the power button line and sending the computer more often than not to shut itself down at the beginning where the power supply is starting cold and is under regulated.
The problem went away as soon as I decoupled the wires. Hopefully this is useful for someone else.
