Hey ! Basically it's my first post here on this forum and I am very desperate about others helping me in understanding this certain PC related problem. So yesterday when I turned on my PC I saw a white horizontal line kind of artifact on booting screen where windows logo appear then I played a game it was fine no glitch or artifact there also nothing was on desktop screen too but as I reinstall the windows and GPU driver the problem goes away so what might the problem can be? Can anyone help me figure out, I'll be really glad to have your opinions and advices. Thanks
