2 months ago I had my hard drive and video card (another name for which I can't remember). Now when rebooting I get a second flash of a question mark. Should I be concerned about this?
Detruis, I went to system preferences, to start up disk, clicked on the HD and clicked on restart. Restarting it made the question mark disappear. Does that mean everything is fine? The computer has been running fine (even with the second flash of the question mark).
