I formatted my hard drive today. It feels good to start fresh again without all the little quirks that a computer picks up over time. The slow loading of LJ comment pages for example seems to have been cured. It'll take me a couple of days to install all the programs I need again and getting stuff set up the way I like it, but it's worth it. Seems the only thing I forgot to copy to an external hard drive was my folder with old email in Outlook. I'm not too upset about it, although I like to save everything like that. At least I remembered to copy the address book.
Some things were lost of course, mainly programs I installed in the lab in Japan. But I don't think I'll have any need to model molecules any time soon. I kind of liked Igor though.
