Black screen because of too many layers?

Hello, I have a problem.. I got a huge project, with a lot of components that I've inserted.. I don't know what the problem could be, but my screen just went black, as if it was too much for my PC to handle. Please help me solve this fast.
I've already emptied out disc cache, and tried to reboot, but none of that worked
Figured 1 thing out.. If I disable layers that are 3-D layered, it shows normally, but if I enable just one of them, same thing happens.
