Hi All, I have a custom built desktop PC with an ASUS M3N78-VM Motherboard. I had Vista installed on it before, and wanted to get Win 7 X64 RTM onto it. I downloaded one of the BIOS SLIC 2.1 rom's for the board, flashed using afudos and off I went... The problem I have is that during the installation of Win 7 x64 RTM, it blue screens just before the 2nd restart 'completing installation'. It blue screens with what looks like an nVidia .dll or similar error (it's too fast to get the full description). I've tried 2 different BIOS SLIC 2.1 mods - 1 of which is confirmed to work by multiple users on here to make sure it wasn't the bios rom causing it. I've also tried to re-run the installation 3 times and each time is the same. The disc I am using has installed fine on 2 other PC's so it's a bit confusing. I've just tried re-installing Vista x64 and that went through all ok. Does anyone know the likely causes of BSOD's at the 2nd restart stage, or has anyone else experienced similar issues? Many thanks, Sansini.
