Y520 - Windows 10 stops loadig when graphic driver loads after last BIOS update

Hello,

My Legion Y520 stopped loading windows 10 x64 after the latest BIOS update. I have reinstalled the win twice and at the moment it updates the video driver the screen becomes black and nothing happens. I have SSD and HDD with windows 10 installed. It is the same on both disks. I've tried to remove the SSD in case it is because of it, but it didn't help. Before the update it was working fine even in havy games. So, I dont think it is a hardware problem. Can someone give some advice? I dont find anything to change in BIOS.

Thanks in advance.

Some people had problems with the latest BIOS of the Y520. You might want to try to downgrade to the previous BIOS.

 

If you need the previous BIOS, check this thread for links.
