Whenver I boot linux in my ASUS x507u laptop , I can not shut it down. this infinite loop keeps going on. I have to force off my laptop with power key. after 3/4 days laptop becomes so slow. thats why I updated my Bios and tried to boot again by disabling graphics card. but it did not boot and this loop showed up again. so I did not try to boot it anymore. any solution ? i dont want to use windows anymore.
