My laptop is about 4 years old and has been running fine until I decided to give it to my sister, so I formatted the hard drive so she can get a fresh computer. All the new drivers are installed and everything works fine, except for the fact that it will reboot itself every once in a while. First I see a blue screen, but I can't read it because it only flashes on the screen before it reboots, and when the system comes up, it says "The system has recovered for a serious error" and then it says "A log of this error has been created" and then it asks me if I want to report the error to microsoft. What is this error? and how do I fix it?
