BSOD after updating Video Card drivers. BSOD continued after reformat.

Just started playing Fortnite: Battle Royale and had a message consistently pop up upon launch of the game, saying that my drivers were old and that I should upgrade (they hadn't been updated since 2015). Since then, I've been repeatedly hit with multiple BSODs. It's my first time dealing with it and can't seem to figure out the issue. I reformatted my main drive twice, still blue screen. Reseated the GPU and move to lower slot, still blue screen. Disconnected all drives but the main, still blue screen. reseated ram and used different slots, still nothing good. Finallly reseated CPU and changed the mobo to an exact same model as I currently have, still nothing changed. I'm kinda stuck as to what may be the issue. Hoping to get some insight. Thanks in advance!

Try going to an older version of the video driver, even going back as far as a Vista driver if you can't solve this with an older Windows 7 driver.

You could also try doing a Windows Update, and if a video driver shows up in the list of available updates, install only that one update.

But in my opinion, the only way you're going to really solve this is to remove Fortnite from your computer. Your problems started when you started playing that game.
