Minecraft Forge Mods Help

I got like a few mods (8) On forge. And It was working fine after a while. Then Bam All of sudden When I was playing around with the mods and I tried to kill a camel (lots o mobs) With an ak-47 (Ferullo's Gun mod) And my minecraft freezes. So i close my mc in task manager and I go back on Minecraft on that world When i try to move, it freezes.I delete the world and start a survival. I go mining And try to mine a copper ore (SimpleOres Mod, I think thats what it's called) Then all of a sudden my Minecraft freezes again. So when I try to do something that involves mods My Minecraft Freezes. Any help? Thanks
