I'm currently running Windows XP on my laptop and after working for a while the laptop and touch pad will lock up. They stop responding but things on the screen keep going. such as a web page loading or a program running so I know the whole laptop has not locked up. Other things on it such as the cd-rom work and such. I have tried to plug in a keyboard and a mouse but it still doesn't respond. I have even jumped over to Linux and reinstalled Windows a few times hoping it might fix it but I keep getting this problem.
