so im on a lenovo y520 legion "gaming" laptop and system update kept telling me to update the bios and well one fine day i decided to. Probably the worst mistake ive made. Ever since i updated the bios, every game would just get a blue screen.

The blue screen showed some different error codes and after some research i understood the code was a driver problem, i went further to update all my drivers and hoping to see if my problem was fixed. Instead of a solution i got another blue screen with a different error code. And i read on many websites as to what i should do. It told me to run a memory scan do everythign and if nothign works just reset to factory. After a lot of tests i had to reset.

And yet, here i am with no idea how to fix the problem. i tried to find the download to the old bios to try and flash back but it seems tho that lenovo deleted that version of the bios for the y520. So im kinda clueless as to what i should do...any help would be good
