Hello there beatiful people of this forum, How things are going for you? Today I'm asking some kind of advice for a  (supposedly stupid) possible purchase, I've seen a laptop with really good specs ( i7 7700 and gtx 1070, 16 gb etc) on a website called subito.it( the italian equivalente of craiglist or ebay) the price is really good ( like 300 euro flat, I live in italy) the only problem is that it has those weird green lines showing up on the display, I would like to know if It is possibile to diagnose the nature of them /what the possible causes could be for them to appear (could be the gpu going bad or maybe just the screen?) , thanks in advance for any help!!

I wouldn't. It's likely a GPU issue.

That's not a display issue, that's a GPU issue. I wouldn't bother with it. GPU failures in laptops can be a pain in the rear to deal with.

In my experience, an unstable display signal wouldn't artifact like that, but straight up become a black screen

 

Artifacts like that are normally caused by GPU, most likely the VRAM side of things

-sigh- feeling like I'm being too negative lately

Personal experience with dead GPUs in laptops for me. The artifacts are pretty distinct.

They probably very much knew the gpu was cooked and try to pass the problem on.
