Ok, I found the splash.properties file, but I'm not sure how to change the enabled-ness of it. But I added the dforge argument. The problem still persists.
Would these files have anything to do with it? I had tried taking them out and relaunching, but they just end up getting re-downloaded and put back in.

Also, I can still run vanilla minecraft so would this problem be a hardware one? I know my lappy here isn't new and fast or shiny, that's one reason why I chose the lite packs to play with. Thanks again for your help, I am a complete nub when it comes to the how it works of minecraft and ftb so your help is very much appreciated!
