    Seemed to just happen suddenly. Went to bed and it was fine and it was like that the next day. I’ve attached a picture of the error screen, it’s the first thing that pops up.

    Could this be something loose inside from dropping or transport? There is endpoint security on it, could it be to do with that?

    I’ve tried a PRAM reset and the only difference it makes is I now hear the start up chime before i see the error screen.

    Anyone have any ideas?

    Everything I can find on the web points to a piece of security software called "Check Point". I would suggest that you talk to them.

    Do you have a Bootcamp Windows installation?
    That boot error looks like something from Windows, and not a normal error screen for anything on a Mac that I have ever seen.
    You said that you have "endpoint security"
    What is that? Is it the enterprise network security suite from Comodo?
    There's nothing about your screen shot that identifies that as resulting from Endpoint.
    Do YOU have a means of disabling, or removing the Endpoint security?
    If your red screen is related to that security package, you may simply need to call your IT support for help - particularly if you know it is something that will lock down your computer. This may be what is happening. So, rather than guessing, I would recommend contacting your support folks.
