Hello, I wonder if anybody can help me, please. I have a netbook (small, low spec laptop) which keeps on freezing. It will not respond to any keyboard input (including Ctrl+Alt+Del) or the mouse, etc. The only thing I can do is hold down the power button to cut the power then restart. I am trying to reinstall Windows to solve this problem. Because the computer is quite low spec, I am concerned that Vista or higher/later might be too heavy, and besides I don't really want to spend money on an OS. Anyway, the computer came with Windows XP Professional Edition installed when new and it has a certificate sticker on the bottom. However, because the netbook is old and has been carried around a lot, half of the product key is worn out and cannot be read. I have gone into the registry to find the product key and I have entered this but the installer says that it is not a valid key! Other key finder programs have told me the same product key so I am confident it is right. I have typed it a number of times and checked it carefully so I am sure that it is not a typo. How can the registry key not be right? So, I have tried to find new product keys using keygens and none of those are accepted either. Why is this? So, I all I want to do is reinstall Windows XP on a computer with Windows XP including an authentic certificate sticker. What should I do? Please help! Thank you!
