Dell Inspiron 7000 gaming

Hey everyone, hope y'all are doing great... I have a Dell Inspiron 15 7577 laptop, precisely the i5-7300HQ version, lately I've been getting a "weird" problem with its keyboard... the keys (2,z,s,x) as well as the CapsLock don't work, but when I plug in a USB drive or mouse or basically anything...

While watching a simple video on fb I got the BSOD Critical Structure Corruption. A similar thing happened when I open a game and mostly happens then for example if I open AC origins the game plays fine sometimes it crashes when I open LoL it happens all the time, after automatic restart it...
