I wanted to make a format, so I put a bootable USB stick in by default, I started the computer again and here the problem was there was UEFI there was nothing. OK, then restart and spam with the key responsible for Boot Menu and UEFI and nothing but black screen. So I found that I would restore the system from the windows but when the computer everything was ready again the black screen for 2-3 hours (then I lost my patience). However, when I start the PC from the beginning there is a black screen, nothing appears and suddenly after about 15-20 seconds the Windows login screen appears. I tried to enable UEFI through Windows in the recovery and restar pc options and it also doesn't work. I will add that I have tested the computer efficiently in both games and benchmarks. The results were similar and even the same as when the computer was working properly (November 2017).
