It already is official 7850v39 from link in my post. I did what you said. SLIC ToolKit// SLIC Diagnosis - 2.1 - OK (It seems fine to me) Thank you Serg008.
Thanks. Updated BIOS successfully. After that, is there anything should I do to activate Windows 7? I'm not currently on it (I'll install later) so I don't know if it's going to activate automatically or not.
