How do I completely re-boot my laptop
I've got an oldish Acer laptop on XP Home Edition, and my friends have suggested doing a total reboot. I realise this will kill everything that's already on the hard drive, but there really isn't much on there as I just use it for writing and the internet. The one thing I do need to save though is my Microsoft Office 2003 package (Word, Excel, etc). How do I reboot the laptop, and how can I do it without losing Office?
(I do still have a triple-use Office 2003 CD, but it has been used 3 times now...)
