I'm running win 7 64. When I turn the comp on it keeps restarting right whe it's at the "welcome"'screen and it just keeps booting. Im able to boot in safe mode but not with networking- I get a blue screen if I try. I have Malwarebytes installed, ran a full scan in safe mode with no error results. I downloaded two other programs that people suggested: hijackthis and adaware, on my friends comp and saved them to an external drive bit win wouldn't let me install them. What are my options?
