Re: There is something wrong with my laptop
does it drop dead when its on the powersupply or only on battery?
anyway, install the following program: speedfan: http://www.almico.com/sfdownload.php
I think the thermal protection of your cpu is doing the trick of dying on you 
Every up-to-date cpu has a protection temperature built in. When the cpu is getting overheated the thermal protection will shut down your computer without a warning.
Just install speedfan and monitor the temperature for a few hours.
I think the cpu cooler isnt working properly or you have too much dust in your laptop air-outtake. Try turning on the vacuumcleaner and clean the air outtake of the laptop with the laptop turned OFF! If this doesnt work you ll have to bring it to any computer store and let them replace the cpu cooler.
If your hubby is good with hardware he can do it himself or you can
Congradulations on shaadi btw MashAllah
