I have posted about this before but I have recently updated to windows 10, because let's be honest, windows 8.1 isn't the best. As I explained before, whenever I start up the game and I get into the launcher, as soon as I press play it seems like the game is starting up but then I get black screen and then it closes its self down after 5 or 6 seconds. I have tried windowed border less mode etc etc and I have even taken the time to reinstall the game however nothing seems to be working. Also, if this does get fixed, if anyone knows how to allocate more RAM to Fallout 4, could you put that below too.

Note: The game was working before fine, I had a bit of lag issues so I lowered the settings down and then this started to happen.

System specs:

GeForce GTX 970

Intel® Core™ i5-4690k CPU @ 3.50GHz

16.00 GB RAM

Current Resolution ~ 1920 x 1080, 60Hz

Driver Version ~ 359.00

OS ~ Windows 10

it seems to have fixed its self now
