So yesterday my PC crashed and i decided to just let it stay off, But this morning when i turned it on it gave me the option to chose safe mode and stuff like that. So i clicked start Windows normally but it loads for like 2 sec a blue screen flashes really fast and then my computer reboots. That happens in safe mode too. I would like to know if there is anything i can do or do i have to reinstall windows. Also could a new Graphics card and Sound card cause this problem as i did add one yesterday.
