Right click on desktop, select nvidia control panel, go through the settings. If you've never changed these to begin with, they are probably already at stock values and this won't help. But it's worth a shot I guess. If you do change something, write down the old value so you can change it back later. You want to set:
Anisotropic filtering - app controlled
Gamma correction - off
antialiasing - app control
aa transparency - off
force mipmap - none
texture filtering - off
texture filtering quality - quality
trilinear optim - off
threaded optim - off
triple buffer - off
force vsync - off
Set those and then try to load the game. If you get to the main menu, set your desired resolution and graphic settings, then exit. Now you can go back to the nvidia control panel and turn those things back on. If it blacks out again, you'll want to reset those options again, then go through them one by one until you find the one that causes the black screen.
EDIT: Congrats! I don't know why that works or how, but thank god it does
