I have the above laptop with windows 7 on it, fresh install.  Problem is that whenever Im running the laptop in normal mode, the laptop shutsoff randomly even with no programs running.  I did some research on this and read that the nvidia graphics chips sometimes heat up and cuse this.  However, when I start the laptop in safe mode, this random behaviour of shutdown does not happen.  So it seems that there is some driver or device that gets started in normal mode that causes this shutdown behaviour.  How would I go about finding what driver it is, if my deduction is correct? 

 

Could there be any other cause

Hi shashman,

 

As you have said this is a "fresh install". " Safemode starts" use limited start-up resources. I would start by analyzing what programs are running

 

at start-up here: http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx?ocid=fwlink

 

Then it  is a process of elimination as to what program is the cause of the issue. It is tedious but by preventing some programs to start will narrow the root cause.

 

Also you could run sfc /scannow using the elevated command prompt. It will attempt to repair any corrupt files found.

 

Since this is a fresh install that alternative is a possibility not a probability.

 

Regards............

To add to that, your first hunch may be correct. When PCs and laptops randomly shut down like that, it's usually caused by overheating of one or more of the chipsets. When you boot into safe mode, your computer is using a generic video driver, not the one it normally uses with the graphics chip. This minimal driver would use fewer resources, thus keeping the graphics chip from working as hard and possibly overheating.

 

But I would still recommend going through the process of elimination recommended above, just to be absolutely sure.

Overheating definitely will cause serious problems and perhaps this is indeed the underlying cause. Laptops, due to their construction of having so much

 

in such a small environment, are prone to overheating issues. From what I understand Toshiba owners often suffer this problem.

 

Maybe you should try methods of increasing air circulation through a fan placed underneath and assuring that all vents are unobstructed.

 

Trial and error may lead to a solution providing all else fails. And maybe you can run it normally. Just a thought.

 

Good Luck

 

Regards..............
