Kali Linux screen is broken - AMD FX 6300 - AMD HD 7870

Hello!
So I have AMD computer (AMD processor and AMD graphic card) and when I boot Kali Linux the OS does start, but screen is really really messed up, I don't have picture, but I can take it, if you will need it, maybe you will know issue right away. Also it's PC, not Laptop. Please help, maybe graphic drivers to install somehow or something, maybe through failsafe, ... Thanks

Definitely sounds like video drivers. Can you use Ctrl-Alt-F3 to get to a console prompt? If so, you can login, and diagnose the problem by looking in /var/log or the output of dmesg.

Okej thanks I will try that, can you do that in Live bersion, because I don't want to install linux again for no reason
