horizontal green white flickering lines in screen
whitish-green horizontal flickering lines on the screen. its Lenovo legion y540, but that device was not in the option so I chose y530 coz its structure is exactly the same as this one. it has Nvidia GeForce RTX 2060. when I looked up the device manager, the display adapter Nvidia GeForce RTX 2060 has a danger sign next to it, but it’s updated. I don’t know what’s wrong there.
the lines don’t appear in the bios window. it appears from the logo itself when I start the pc.
I called Lenovo support, they think its software issue and windows need to be cleanly reinstalled again. but I read here and there that it could be the fault of loose screen connection as well, I don’t want to reinstall everything coz its a big step and it takes so long.
can someone tell me if its really a software issue or some hardware issue?
