Wer hatte die gleiche Frage?

HI, I have this issue from the day i got the laptop. I have reinstalling the windows for 2 times, i have reinstall the video driver for several times too and nothing seams to work. For what i can see here, people are talking about the BIOS. My current version BIOS is N.1.14M EC version 0.27.00. Can anyone can tell me if there is any BIOS update i can make and where to find it? Ohh yes,my MEDION Windows Diagnostics app can`t provide me with any download links for any drivers.
