My screen on my Lenovo lap top started opening programs yesterday by itself - like someone had access to my computer. I had to keep rebooting it, but the reboot would only last for a few minutes then I would have to reboot again. Today, my computer screen is pink and I had a message to reboot Windows, but there is nothing I can click on...nothing happens. Now that screen is in the background of whatever I have open. How can I fix this? Please help.
