We had the family computer cleaned over the course of the last three days. Of course, this meant that none of us had access to it, since it'd been sent out for that, but now it works much faster than it used to. We're going to have to reload a lot of files from backup, though, since only the basic programs were reloaded when the computer was returned.
It kind of sucks to have to do that, but the computer loads a lot faster now. So that's nice, it least.
