Good night, guys, I found a graphics card compatible with my laptop. It is a GTX 670m out of a msi GT60. The seller said it was 1.5GB, but according watching their vbios is 3GB. Well. With the original vbios, I can see hdmi, vga but no display on the screen of the laptop. (Black screen). If I flash the vbios gtx 570m. The screen of the laptop, illuminates, but still black screen. VGA and HDMI are seen, but with errors on screen. I am very desperate to run this notebook. He has now 3years in my closet ... Can you think something happens ?, vBIOS customs? something ?. Thank you. EDIT: More info, MSI GT780DXR, BIOS 10H for non raid systems. And i look in nvidia and i cant look a laptop screen. With my graphic card gtx 570m i can look. EDIT2: I Update the bios and firmware. GT780 MS-1761 Bios ver.: E1761IMS.10H (NON RAID SISTEM) Bios build: 11/18/2011 10:10:10 EC ver. : 1761EMS2 Ver 4.19 EC build: 11/22/2011 ME FW ver.: 7.0.4.1197
