How to fix this 1.7.10 Forge problem?

I have 1.7.10 Forge on the Minecraft Launcher and every time i try to load it it takes me to a black screen where the Mojang name usually pops up then procedes to take me to a screen that has 1 box in the bottom left corner of the screen. This box has the usual Minecraft Title Screen background on it.
The rest of the space is just white and i can't seem to figure out how to fix it. All advice would be apreciated. I tried switching versions and it worked normaly then i switched back to 1.7.10 and it had the same problem. I'm not sure if it has something to do with the mods or something more in depth. If you need the list of the mods and other details just ask.
