I accidentally clicked on a add trying to get rid of it and immediately caused a "blue screen" and computer shutdown. Computer now cannot fully boat up to windows. As system starts up, it goes to blue screen and shuts down again, restarts and the process repeats. Sometimes it will get to login screen but when I login, it takes me to a black screen with only a mouse. Was able to get into Windows a few times with safe mode. Scained with spybot and superanispywhere with no success. Also tried a system restore with still no success.... any help? Thank you so much!
