My laptop keeps glitching (colorful and black and white lines on the whole screen). When I adjust the screen, sometimes I can find "the magic spot" but if someone so much as touches the stupid thing it starts glitching again (or if I leave it alone, it will gradually start glitching again). This has been happening every day since I've gotten it and I even turned it in five times to asurion who have said that they can't find the problem, send it back, it works for one day, and begins glitching again. I'm a little tired of this cycle and would like to know what's actually wrong with my computer if possible. Thank you!
