I recently purchased a 7750 which has no output via DVI connection, on VGA and even at VGA it won't boot to Windows or Linux. I filed a complaint via PP for refund and he wants the GPU back. I would like a refund first and if I do ship back, want the costs of shipping back. I have PM'd him multiple times and only got 1 response. I finally got another response after PP resolution request. Please advice. Thanks.
