Laptop black screen after updating Drivers

[notdrakken]

I was updating the drivers of my Lenovo Legion Y520 the other day and installed them all, after restarting my laptop it works normally until I enter the password of my account, all that pops out is a black screen and a system32 command prompt appears.
I cant do anything other than look

Hi, unplug the adapter and remove the battery, hold the power button for a minute. Reconnect the adapter and start the laptop.
