With the acquisition of a new laptop, I've recently moved from an external broadband modem to a wireless router and although both machines have been fine for a while, the windows 2000 PC has not been able to connect for over a week now, and given the performance problems I've been having, I've decided to upgrade to Windows XP. (The XP machine isn't having any problems, so its got to be something to do with the W2k machine).
The thing is, I don't know if there are any nasties still lying around from last year's virus that might be causing the poor performance, and I've been thinking that the best thing to do will be to reformat my hard drive.
Has anyone got any advice about whether reformatting will help, or if it's likely to cause more problems than it solves? Should I upgrade first and see if that improves performance, and only re-format if it doesn't? What pitfalls should I look out for if I just upgrade without reformatting?
I'm planning to do this at the end of next week, and I'd really appreciate some advice. The PC should still have some life left in it but it's getting to be a pain to use.
