Computer Is Not Connected To Internet

I inserted a blank CD to add music into, using iTunes 10 (maybe 11).It did the job but all of the music were incomplete and the lengths were like 8 or 6 seconds.I tried to format the CD but it didn't work.Then I got angry and smashed the keyboard, and it froze.I force shut the laptop WITH THE CD STILL INSERTED and ejected it, then turned it on again.Windows started Startup Repair and it finishes, then restarted.And again Startup Repair ran again, then it told me it can fix the problem in a new dialog box.My computer is not connected to the Internet and I'm using a substitute computer to type this.A box in the dialog box showed the following text: [code] I closed the dialog box and it told me: (translated from Japanese, may not be that accurate.)

If you connected devices such as cameras or portable music players to this computer, please ejected them and then restart the computer. If this message keeps appearing, please ask the administrator or the manufacturer of the computer.Then I click Finish to restart.And again Startup Repair showed up, and the same message showed up.I clicked something like Show Restore System Option to restore the system, but it says the restore point is broken during restoration, and when I try to restore the system again, it still doesn't work.
