Hi everyone,

I own a MSI PS42 Intel i7 with 8GB RAM.
Last week, while I was doing light tasks such as navigating a web, my system froze. I had to boot the system by force pressing the booting button (🙂 English is not my main language).
Today it happened again. I reboot the system but then it kind of collapsed. I could not get past a total black screen. No GRUB visible and no changes in that black screen even if I press the Shift or Esc button.
I have tried recovering the GRUB through a pen with 18.04 ISO, but the computer doesn't react.
The buttons are lighten up, which shows it's on, but the screen remains black.
I haven't found any solution when it doesn't react to the usb pen.
Can please somebody help?
Long live Ubuntu
