Hello, My dell R710 still "died", He stays at configuring memory or something. sometimes i don't see that configuring memory then that is black but i see the bios F11... and i tried cold boot, warm boot...
I wil give you a gif of 25 seconds to show what he says if you guys have any idea what i can do, please let me know!
