At first, my computer has been running smoothly. Until suddenly it shut down for no reason. No, there’s no power interruption or what so ever that caused it to shut down. When I pressed the power button to restart my computer, the red LED flashed, it means the power is normal. But before it reaches its revolution per minute, it shuts down again.
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.
