How exactly pisses you off when your the one giving it for free by posting it on public?.
How do you want the people who saw your post, want to give you something that You did not even request what you want in returned.
When I look at the guide its pretty much the same as every other Scam Guide on ebay/Amazon. That why alot of people got banned on Amazon for doing this tricks. Mostly people go for GPU..
I also did this and It works But mine was different. I had old GPU 1070 that is not working anymore and Bought a new one *same manufacture+model*. Then I called Zotac (same brand as new one). I put the old GPU Inside the new one I just bought then ship it back. I got new one again. You must clean the Old gpu dust free + there is a warranty sticker. U switch the warranty sticker apart. (Safely remove them with heat gun).
