Windows 10: Booting to black screen - Windows 10

Restarted to finish installing Windows 10 updates, booted into a black screen. Boots into a black screen now every time I try to boot into normal mode.
Ran Windows 10 fine since it was released. Never had this problem before in five years of using this laptop.
It boots into safe mode fine, so I figured it was a problem with my graphics card. I tried uninstalling the drivers and the card, but the problem persisted.
Eventually I gave up and reformatted the whole system using DBAN. Reinstalled Windows 10 fresh. It started up fine, but the resolution was wacky. I figured the GPU wasn't working, so I brought up the AMD website to install the necessary drivers. Suddenly it flashed to a black screen again. Now it's stuck on the original problem again: booting to black screen repeatedly.
Tried reformatting again and reinstalling Windows 7. Installed and booted up fine, but again the resolution was wacky. Installed the drivers for the GPU, and it black screen again.
Pretty stumped here. Any ideas? Or am I dealing with a trashed GPU?
First post here. Thanks for your help!

Are you able to see the BIOS screen or the Windows logo?

What is the make and model of your computer?

Hi, if you'd only been dealing with one OS the suggestions could have been fairly straightforward. What puzzles me is that you also had problems when installing Win 7; as you know, you shouldn't have had to go looking for a graphics driver after installing Win 7.

Did you install a graphics driver from your manufacturer's site (Win 7 case)? Graphics drivers e.g. generic ones are not guaranteed to work on a laptop. Noted you referred to the site earlier.

Is the display ok in safe mode under Win 7?

Have a look at the Event Viewer and see what the log tells you. You may find 'Whocrashed' (easily findable, free) gives you a simple view of driver events.

I think what I'd try is - if you're using BIOS not UEFI- get yourself a (free) boot CD (Falcon's, Hiren's etc- easily findable on the internet) and boot from that, and see what happens. Those disks contain quite a few diagnostic programs, so you may find something helpful.

Even if you have a boot disk for a partition manager, for example, try it and see if your display is stable.
