Why does my computer turn itself off?

I have an old laptop with Windows 7 system, and I want to use it as a home server. I put it under a desk, and control it via Remote Desktop Connection on a MacBook Pro. Both the laptop and the macbook are connected to my home router.

It works almost well, except the laptop is keeping turning itself off. About 3 times in a week. On mourning, when I wanted to connect to the laptop, I found it was down.I checked the event log on the Windows 7, and I found it was off almost the same time I turned off my macbook and went to sleep. I don't know why and how to fix it. Can anyone help me figure out what cause the problem?

1Look under the power settings and disable the shutdown after some time of inactivity. Also look in the eventlog for details why Windows did the shutdown. – magicandre1981 – 2013-03-24T05:54:05.180

One of this parameters can be your problem:

Power Option Setting in control panel.
Hardware problem (CPU Fan, Battery, Laptop Power Board, ...).
Other software which you installed.

you can install ubuntu or other linux and check your laptop, If turn off again your hardware have a problem.With cpu-z and gpu-z application you can check your hardware temperature and other detail.

Is there any log file I can check out why it is shutting down? – yang – 2013-03-24T11:38:40.003

it was hibernating. I turned the function off, and now it is ok. Thanks. – yang – 2013-03-29T10:05:56.357
