How to get off black screen?

I think that your HDD might be the issue. You might want to replace it with an SSD, they’re much faster and it will make your laptop work much faster than before. Although if you do this you won’t have access to your old files, so what I’d recommend you do is buy something like this https://www.gearbest.com/cables-connecto... (It’s a Sata to USB cable) and once you’ve got your SSD into your laptop, copy the files from your HDD using the Sata to USB. Remember you’ll also need to download a new operating system, you can get Windows 10, and Linux based operating systems for free. But older versions of Windows will unfortunately cost you some money.
