Yeah, My computer was working fine a couple of days ago. All of a sudden it shut off. But the green light still lit up, indicating that the computer was receiving power. So i opened up the case and blew it out. After this the computer worked fine for a few hours. Then it shut off again. And ever since it won't even start up the OS, it only runs in safe mode. What should i do? And please ask me if you need more information.:4-dontkno By the way i already ran some virus scans, nothing found.
