    Hello, long time member that rarely post but I read a lot lol.

    The problem I'm having is my MBP won't boot from the internal hard drive or usb stick or drive, what I get in a flashing folder with question mark. Its not the hard drive, I took it out tested it on a different computer and it works fine. I'm also going to rule out the internal cable because when I use the usb (both port) with a external hard drive or flash drive and hit opt (alt) it does not work, the flash drive or light on the external usb hard drive flashes fast and I still get the flashing question mark. It also does not boot from the super drive.

    Any help would be great..

    thanks

    2010 MBP 13.3, 2.4ghz

    Trust me that is not my even close to being the issue, wish it was. that was first think I tried.

    Anyhow, it seems the memory slots and keyboard is part of the issue.. What I did was swap in two different ram from my other MBP, same result, then I tried only one in the bottom slot and I got a beep. next tried the top slot and it booted up but still got the flashing folder so I swap ram and it booted up fine.
