Preparation:
- They will want to know what motherboard, CPU and GPU you have, make sure they are all compatible
- They will want to know wattage of your PSU make sure the PSU you say is at least 750 watts
- They will ask for a serial get one from eBay.
- They might ask for pictures grab them from eBay.
Step 1) Find a serial number (I normally look on eBay for these)
Step 2) Go to the support link for your country, in the UK it is:
https://nvidia.custhelp.com/app/chat/chat_launch/
Step 3) Make up some rubbish story it wont work you tried a different GPU and that worked.
Step 4) You are going to need to fake a receipt one of NVIDIAs main stream resellers (NewEgg, Scan etc etc). If you use a random store you will fail.
Step 5) They will ask where you bought it from say one of there authorized resellers.
Step 6) They will want you to upload your invoice/receipt and then return the item.
Step 7) Once invoice has been approved simply return your item using a trusted boxing service or custom address scan.
Step 8) Contact them after a few days of delivery asking for an update it has been delivered.
Step 9) They will raise an investigation and then ship you a RMA unit out.
Simple as that! Most people get confused on the authorized reseller part then give up.
For higher success get a real invoice from Scan or NewEgg, simply order the GPU you are going to SE then return it as soon as it arrives, or cancel the order straight away but if you just return it then you get the invoice in physical format and the serial and exclusive non edited pictures :)
