Hi Everyone, I have tried all the solutions mentioned by apple and still have a white screen with a blinking file folder with a question mark in the center, anyone have any ideas or experienced this?

Your Mac has lost track of what Startup Disk it i supposed to be booting from, or the startup disk specified has probelms.

Try Holding down Alt/Option at Startup, and wait while it slowly draws an icon for each potentially-bootable Volume it finds.

Nooo or you would use OS X Recovery Mode: Disk Utilty and then Startup Disk.
