That would be a RAM failure. Have you tried reseating the RAM? Also try one RAM module at a time and try in each RAM slot.
my Dell G15 5511 laptop isn't starting, it doesn't even show the Dell logo, so I don't think the system is booting up. The keyboard backlight comes on and doesn't turn off. The small led dot that shows that the laptop is charging, flashes white and orange sporadically. The fans are spinning and stuff. I don't know what to do. If it helps, yesterday there was a random Bios update that right after I started it. It updated it and started normally, I even used the laptop for a few hours :') Anyone knows what is going on? ಥ⁠‿⁠ಥ
