The ultimate Windows fix;Letter
So, I backed up all my work and downloads (and I have a couple of hundred megs of those) and reformatted the hard drive. I have two hard drives so backing up is a doddle, though, if you don't, you should simply have the whole process carried out by a professional with a ZIP drive or a laptop to back up your work.
You have to reinstall most of your software, but it gives you a proper chance to organise your system more efficiently, and you will find that all those programs that used to crash should probably work without a single hitch, with the exception of Microsoft Internet Explorer 4.
I know it's a drastic step, but if you constantly remove and install programs, it's well worth doing this every six to 12 months.
