Disc drive stopped working awhile back now windows won't boot
A few months back, my desktop stopped reading discs. I can't burn discs, either. And now, overnight, I went to use my computer and it all of a sudden restarted and now won't boot. I have looked around and since my computer was given to me, I don't know the administrator's password. The person that gave it to me doesn't know it either. How can I fix my computer? I am obviously not too computer saavy, so simple terms would be appreciated.
