Minecraft Forums

I recently put around 30-40 mods into my mods folder. It will no longer open I have no idea what I've done wrong, I've done this before. I downloaded the mods mostly from curse, some from 9minecraft. Same as usual I've used almost all of the mods before, I just Factory Reset my PC so it could be anything please help. http://pastebin.com/uEbvjR3T

UPDATE. In an attempt to find the solution myself I removed all the mods and began to put them in one at a time. it told me to put in cofh core so I did. Then natura and forestry. Then Mantle. When I put in Mantle it crashed. Here is the report.

some from 9minecraft.

NEVER download mods from anywhere except these forums, curse, and sometimes the mod's website(which will usually be linked in the MCF thread).
