At this point, I started to think of the possible hardware mulfunction.  I open up the casing and started to disconnect all the plug and play peripherals.  To ensure no further damage on data stored in the hard drive, I disconnected to power and data cable for the hard drive and restart the competer again.

This time I am facing the motherboard while pressing the power button.  I was amazed to see that before the CPU colling fan reaches its normal revolution per minutes, the PC sguts down again.  I statrted to check the power supply, sus[pecting that it might supply not enough power on the motherboard.

After some testing using my digital tester,  i did not find any malfunction on the power supply.  Ths time I am beggining to suspect the motherboard.  Again, I disconnected the the cd rom, though I have checked the power supply, I want to make if there’s some error in the motherboard.

On fifth time of resatring the computer, I noticed that there’s someting unfamiliar in the power button switch.  I tried to push it again and somehow I felt it doest bounched back.  Now I am begining to smile.  I decide to remove the switch and replace it with the reset switch.

While checking the switch, i found out that it the one making the computer to restart again and again after pushing it.  It took a lot of time, but a worth while experience.  I did not think that the power switch is the causing the PC to restart.
