I have a Fujitsu Siemens Laptop with Vista Home premium OS and intel core duo processor (T2450- 2 GHz) and 2.5GB ram my problem is that my laptop just freezes in the middle of something either when surfing or trying to open an email ar any other file. The screen that I am on remains displayed but the computer does not respond to either mouse clicks or any other function keys the screen just remains frozen. I have to switch off and then turn it on again after some time and the windows option to start normally is displayed that I accept and computer reboots into windows. Can anyone help/ advise what could be the problem
