I tried searching for this, but the topic is too vague for me to try to find an answer. Anyway I am wondering if you still have warranty on the CPU that you bought from someone else? Do you need a receipt for the RMA process?
What if you have the box, but do not have the receipt? Someone is helping me obtain a CPU from MC. Can I just ask the person to also send me the receipt and this would work to prove that I bought it? I am beginning to wonder if this is worth it. I am not comfortable not having warranty on any high priced electronics.
