Macbook Pro keyboard unresponsive - causes screen to flash
My Macbook Pro seems to have an unresponsive keyboard. When I turn it on, it loads to the login screen but does not allow me to type my password to log in. Every key stroke causes the display screen to flash. Toggling on/off the Caps Lock also does this, however the green light does light up on the keyboard when the Caps Lock is turned on. I have rebooted, ran Disk Utility and even attempted in Safe Mode with no remedy. I am running OS X Yosemite.
MacBook Pro, OS X Yosemite (10.10.2)
