'''This is my answer to '''[http://www.ifixit.com/Answers/View/58167/Freezing+on+startup%2C+freezes+for+anything+to+do+with+the+guide.#answer58250|Another Question]:
"This is usually a pre-cursor to the Red Ring of Death, or an e73/e74 error. I suggest installing a [product|IF205-024|Red Ring of Death fix kit], which should fix the problem before it turns into the RROD. [guide|3550|Here] is a guide that should help you through the process."
And you're right, this is an early warning for the of the RROD.
