Two days after renewed guarantee runs out so does computer screen. Whatever is on the current display burns into the background of the next screen you go to. So, if you transfer to another screen, you will also get to view all the past screens' images. Start with the startup screen, click on Amazon.com, go to youtube.com, then check your mail; all the different screen images appear together making for an unreadable mess. The screen never erases or completely clears the old images in favor of the new image. I will never waste money on a renewed computer.
