Please do not make multiple threads about the same topic. If you need more advice on an old thread, "bump" it to the top by just replying to it and simply say "bump".
As for your issue, I agree with what the other person said in your original thread. If it is not that, my guess is you have a bad wire somewhere causing your computer to put you into limp mode.
