On start up I get a file with flashing question mark
I ordered a new DC input board from iFixit to fix my problem and my neighbor said she would clean up my computer before the part came in. Now the system will not restart and all I get is the file with flashing question mark on startup, I have tried all of the recommended correction and have gotten nowhere. The one thing I note is if I start up the computer with the option key down, I get a recycle arrow on the left of the screen in a square and a right arrow in a square on the right of the screen. But nothing happens. Can you help me here? Charlie
Is this a good question?
