Hi @Dragoshhh ,
I believe the best solution for your case would be to return the unit to the workshop informing the problems you had with it.
If you want to try to solve the problem yourself, please check this link here with insights on how to solve Blue Screen Problems.
For BIOS updates, we always recommend you to use the Device Manager tool. Right click on start menu -> select device manager from the list -> right click on firmware -> select update driver -> use the automatic search option.
If there is a BIOS update available, it will be installed
Drivers updates can also be performed via the device manager, by selecting the specific driver and following the same procedure.
Automatic Windows updates also install the latest version of these drivers so keep your Windows updated to its latest version, including optional driver package updates.
Regards,
Gehringer
