I think this PC problem was solved with a prayer. Read first before you say 'corny'.
I was normally surfing online when I noticed my battery monitor -- I was running on it, not with electric power. I tried to fix that then my PC suddenly shut down. When I tried turning it on, it would shut down again at Windows load. This happened about 10 times before Windows gave me the option of checking Startup. I allowed that and after the check, Windows said my 'registry is corrupt'. I thought how could that be when I stopped tweaking my registry a long time ago knowing it's a no-no. Windows allowed me to restart, did that, and the PC shut down again.
I tried turning it on again and again but it was no use. I gave up and assumed that my registry is indeed corrupted. I rested then tried blowing dust inside the PC away to make sure overheating is not the cause. I was taking a bath when it occurred to me that since the problem started with power malfunction, maybe the problem is my outlet socket.
My power adapter is connected to an octopus outlet. I took away the multiple outlet and inserted my adapter directly. My Pc turned on and worked again. That simple. It was just another 'false positive' from Windows -- again.
My analysis: either my socket malfunctioned or a hacker used the socket. Hackers could do that -- especially when you’re on power smartmeter.
The Importance of Dusting Inside of PC
You're working on an important manuscript you haven't saved. Then suddenly your computer screen blanks out. There is no possibility of recovering any file you haven't saved when that happens.
I was lucky when it happened to me. I just tried to restart five times then my netbook went normal again. I researched how and why it occurred and the answer I found was so simple it surprised me: Dust stopped the fan inside netbook and overheating crashed or blanked it out.
So if ever this happens to you, don't panic and call your techie at once. Try first the tutorial below which is the most probable answer.
