It don't boot with the 2700+ at all.. With the 2200+ it POST and then Windows XP starts (the XP screen) but it don't finish, I don't think it freezes because the progress bar(?) still shows it's loading but it hasn't finished (been showing the same screen for over an hour). Tried shutting down the system, unplugging the tower and not sure what else to do. The POST shows the 2200+ and everything looks good on startup. Any suggestions?
