Check and see if its getting hotter than it use to...If so it might need to be cleaned or the fan replaced...the only cheap solution that i could think of is like I had a friend do when he had this prob...Get a usb cooling pad for it...places like compusa or other computer dealers norm carry one..search online and look for lap top colling and you should pull some good ideas...the other prob could be a virus or spyware...they can over load the system and make it just shut down to save its self...but from what i read it might be overheating..
Try to replace the faulty cpu fan replace the faulty main board try to remove virus and spywares with updaed antivirus and spyware remover use the laptop in minimum temperature and humidity Jaswinder Singh Kaloty
Mine does the same thing. But when I run it with an external keyboard, it doesn't freeze. I have replaced the keyboard, the hard drive and the power jack (burned to toast), to no avail.
I have the same problem. I think it is a bios issue, regarding powered mode and travel mode.

or :
Go to C/windows and look for a folder called Faultlog.txt. Open it and it should display all the faults that have occurred. Post a few so we can see if theres anything in particular thats causing it.
OR:
i would suggest that you reboot and get into Windows. Press [Ctrl] + [Alt] + [Delete] and click Task Manager. On the Performance tab, it will give you a reading for the amount of processor usage (which should only be a few percent when the system is sitting idle) and another counter for the amount of memory usage (this should be 192Mb, i.e. 196608Kb, or less). Minimise Task Manager.
When your PC starts freezing or looks like it's about to (if you can tell when it's going to happen), then try and bring up the Task Manager window again from the taskbar at the bottom of the screen. Has the processor usage shot up? What has happened to the memory usage? You might need to resize your screens so that you have the Task Manager running at the side whilst you continue working - that way, you'll be able to keep an eye on what's going on.
Give us some feedback about your results and we'll try and diagnose it further :)
and please if my solution was helpfull rate it as SOLVED

hi there, my sisters dell laptop does the same thing. My best guess is that a hard knock on the graphics card and knocked a few pins out of it. This is something that a average person can not do. My suggestion is to bring it to a computer shop and tell them that you think it's the monitor connections.
