    Hello Gail,

     

    It sounds like you can hear your Mac start up, but you do not see anything on the screen.  I definitely understand your concern with this.

     

    I found an article with steps to troubleshoot issues with displays.  This article is for internal and external displays.  I wasn't sure if you were using a Mac Pro or MacBook Pro from your post.  If you are using a Mac Pro, follow the steps for external displays, but if you're using a MacBook Pro, follow the steps for internal displays.  I recommend reviewing the full article, but this step specifically stands out to me for the issue you described:

     

    Reset the system

    You can reset the Mac's parameter RAM and SMC.

     

    You can find the full article here:

    Best,
