I've decided to update my graphics card drivers. This is what i did: 1. I downloaded the latest graphics card drivers from AMD website,
2. I installed it choosing optional latest driver,
3. I blocked my system with Win + L and I went away,
4. I came back and there was nothing. No installator, no process, so I thought that the installation is complete and I have to restart my computer (Windows GUI was lagging). I did it and first what i've seen was an error. I clicked "OK" and computer has restarted. And now my problem: I see nothing on my display, there's no signal. Even in BIOS. I'm 90% sure everything is working fine because when open BIOS by pressing delete button and after I turn my computer off, it does it faster than in case when i let system start.
