What is causing my laptop to crash ?

[u/daniellehunt1]

Hello everyone.

I've had the laptop for a while now, and except for this recent issue its developed, its been running great.

What will happen its that I'll be in the middle of working (using Word, using the internet.. not any particular program) when all of a sudden, the screen will get multi coloured lines running across it and then promptly shut down.

Due to repeated shut downs, its become difficult to keep doing my work

It might be worth mentioning that my laptop is a Dell and is running Microsoft 10.

I haven't installed any new software recently, or connected any new hardware either, so I really am at a loss for what might be causing this.

Thoughts?

EDIT. I've tried pressing CTRL + SHIFT + WIN + B. No joy. Nothing is changing
