Newegg has your purchase on file. You'd just
have to go log in to your account, go to
purchase history, and request an RMA. It'll go through some prompts on why you're returning it to decide if you need to be charged a restocking fee or whatever.
You can print your invoice off to send to the manufacturer if they need a receipt for warranty support. Good luck
I gotta say henydiah, your very consistent with your posts. Consistently wrong!
You cannot return a cpu to Newegg unless it's within 30 days. They do not charge you a restocking fee either, it would be a swap out for the same part, if it was within 30 days.
You can send it to Intel/AMD if it's within 3yrs and it's a retail cpu. Most OEM cpu's only have 90days-1yr, depending on whether you bought it from a certified reseller or not.
Chances are 99.5% that there is nothing wrong with your cpu though and you would just be wasting your time, and/or they would test it and just send it back to you and tell you there is nothing wrong with it.
Why don't you post your problems on a new thread and see if someone can help you diagnose the real issue.
