I have a laptop : Acer 4736G, using Windows 7 Home Premium 64 bit.

I use this laptop for web surfing and typing document only, no playing any game.

Recently, I encounter the following issue:

When I typing on the Micosoft word, the computer suddenly turn off instantly by itself, Iwithout any warning.

I power on back the laptop, and it work fine again. But after ~ 1 hour, the same incident happened again.

These type of incident happened on these ways:

1. It turn off suddenly when I am surfing the net, typing a document, or do nothing at all.
2. Sometime, when I press the ‘power on’ button, it can turn off suddenly before it reached the ‘windows log in page’. (Sometime this thing can happened few times continuously before I can successfully log into the windows)

I read few recommendation from the internet and I have done the following but so far it still not able to solve my problem:

1. I reformatted my computer, but only C drive, and reinstall the Windows.
2. I swapped my 4G ram with my friend’s ram.
3. I opened out the laptop, and cleaned the cooling fan, heatsink.
4. I installed the software which can measure my CPU, GPU, processor temperature, but the temperature is normal (around 45-60 celcius) . I suspect it is not due to heating problem, because got few time, my laptop suddenly turn off was my first time turn it on in the morning when I waked up from the bad. That time, my laptop turn off suddenly before it reached the ‘Windows log in page. That period of time ~1-2 minute, so I ruled out the heating problem.
5. My laptop can suddenly turn off even it was inside ‘safe mode’.
6. However, if I turn on the laptop and enter the bios page, and leave it there, so far it never turn off by itself. I tried to leave it in the bios page for 1 hour, and it is ok.

Does everybody encounter this type of symptom before? I appreciate your valuable input. Thanks in advance.

I'd suggest going to Start>Control Panel>Administrative Tools>Event Viewer>Windows Logs>System and check for events at the time of or just before the last shutdown. If nothing jumps out at you, review the other Windows Logs and anything under Custom View.

If it happened while you were typing then it would not be a normal event. Does it happen when plugged in or only on battery power ?
