When I started the computer the previous owner had reset it back to the factory default state, so it said it needed updated drivers for the video card, network card etc...maybe five different drivers in total.
I haven't been able to get it into safe mode. I've was able to do a memory diagnostic which came up fine by hitting f4 before the laptop boots and freezes. F4 also takes me to the option to do a system repair. I'm currently running a basic system repair rather than the full one but it is taking forever (a hour plus so far). It's moving but very slowly.
