Random Black screen

[dannyburlo]

Hi, hoping someone can help. My computer randomly black screens when I'm just casually using it, i.e. browsing internet, watching YouTube, browsing through steam. The screen goes black but sound still plays for a while. I can be gaming for hours and the pc is totally fine, no black screen.

Is this my psu? Or GPU?

Specs:
I5 3330
Rx 460
8gb ddr3
450w psu

Have you gotten any certain error codes, if so it could be loads of things your GPU, monitor or even the PSU. Also what PSU brand is it?
