Windows as far as I know, is the only OS that needs a reinstall from degenarating on its own, I just got done fighting the many freezes I am sure has happened to many of you. I cleaned the reg. & old app. data & I have been on for a while without a prob. I am sure it is just luck though, next reboot the whole thing will start again, I am just wondering why does it do this when you only surf safe sites & don't do anything risky to my system.
