wont load login screen

hello, my friend has given me his laptop to have a look at, the basic problem is that it wont load the login screen, it just goes black, it did give me the options to start repairs, but then it just went black again, now when i turn it on nothing happens, from what i can tell its to do with the drivers but how do i get to install drivers?

I have the same problem with my Acer aspire 5516
