Answer to "My computer screen is just turning white on startup?"Hi. My laptop has been unused since Feb this year. Actually, the half of my Acer monitor laptop had turn white. At first, the computer always lags and hang up. Then after a day, when I was downloading a video clip for my sister's project, my laptop turned black and then the screen became white on top and black on the bottom. When I let the laptop on for hours, the white fades slowly but the background sticks to the white area whenever I go to another page or folder. I also tried reformatting the laptop but it always says "There is a problem with your PC. Go to back to your startscreen". I was too scared of what to do. I didn't believe that the screen needs replacement as the technician said. I am hoping that this is just a cause of the nasty virus from an external hard drive I used from the office I worked on.
