Question Horizontal white blocky lines appearing when playing games

[mattatcomputer]

I bought a unopened HP Pavilion laptop from Ebay with a gtx 1650 and Ryzen 5 5600h. I've noticed when I play games, mostly Overwatch 2, seemingly at random, white blocky horizontal lines will appear about 2 inches in length, usually near the centre, and will dissapear very quickly. It's not really that bad and only happens at most three times a game but is this indicative of a hardware problem that may get worse? I have updated my Nvidia drivers.

Could have been a glitch, but something to watch over time.

Test with a benchmark tool like Superposition (1080 Extreme profile) and see how the system reacts and how hot it gets.

For some reason this program seems to think I only have 512mb vram but the card has 4gb I think?

That would be the AMD integrated video controller, not the Nvidia.

Ah right that makes sense. I couldnt see a way to switch it round in the program but will try again later. In games it's definitely been using the 1650 and in other benchmark tools Ive used.
