Hi I’m a newbie, I have had an evga 9600 gt in my home built system for years I recently bought an evga gtx760 Acx because I have a non uefi mobo “intel s975xbx2 with latest bios 2838” and that was the latest card recommended. When it boots in any configuration with the 760 installed it posts, I can get in the bios and then black screen with cursor blinking in upper left corner and nothing further. win 10 os. I don’t know what other information you need but I will try to provide it. Thanks in advance
