Hangs on boot (Fresh install + Updates).

edit

I get blank screen after updating my pc. Boots to repair mode.

This affects also Ubuntu 16.04 installation. Ubuntu also boots with repair mode and nomodeset added.

Did even fresh installation with Fedora. Boot right with installation, but after updating packages it's broken again.

Bootloader boots, after it boots kernel: numlock key activates on keyboard and display says no signal. Can't press any key (num lock is locked can't press caps lock). Repair mode works.
