It just stays blank after showing my motherboard's brand. Not just that, but when I used to have dual boot, when I restart my PC after the blank screen, it took me to the BIOS menu, with Lubuntu missing. I tried recovering by different methods, but after the 4th try, I gave up and just kept Windows 10 alone. I assume it could be my SSD, but even if that was the case, what am I supossed to do? It occurs ocassionally since a few days after I built my PC, but this week alone happened 3 or 4 times.
