I am running Windows 8.1. After restarts, the laptop screen would be blank, yet the computer would load. If I hooked up a 2nd monitor, it would show the desktop on that screen but laptop screen blank. Now when I try to type on that computer (I'm currently on a different computer) the typing of the keys is all off (none of the letters actually type what they are supposed to and some open up random windows and command prompts) I am wondering if this is a virus. Currently running Malwarebytes. I did a system restore earlier and the problem wasn't solved.
