laptop shutting down on its own

[Nikhil_21]

My lenovo laptop suddenly shuts down on its own just after few minutes of operation. I can hear the fan sound and its not the normal sound as it was in earlier days. But it is not getting that hot. I was trying to install some temp monitoring software but in between the installation only it shuts down. Please suggest what to do?

Now i noticed one more thing : I started my laptop and did nothing and kept it on to see how long it remains on. It remained ON for more than 3 Hours, than after 3 hours I started doing some work on it like opened browser and downloaded something. Then it went off within few minutes. It may shut down doing anything like scanning, installing some software, playing video etc.I think temperature is not the problem.

Can you boot to safe mode and see how it acts?

first of all thanks for your reply. About the problem I would like to say that I am facing this problem from past few months. So I have tried booting it in safe mode few months ago but I remember the result was same at that time. But since its a long time I will try it once again and see how it reacts this time and let you know in a while. Right now I am running memtest86 to find if RAM is faulty as I came across this solution over internet.

If it does boot OK, might try upgrading BIOS and drivers

The problem is still there in safe mode also but I found it remains on for more time in safe mode as compared to normal mode.

Check temps as well as for virus and malware
