When I try to power up my brother's pc the Windows logo appears and the spinning circle starts spinning. But then it just keeps going. It doesn't freeze or anything it just loops.. This began out of nowhere. Last time it worked, we replaced the fans and now it refuses. Anyone has any idea how I can fix this?

It seemed to be a cable that came loose. When I checked all cables, it booted again. Thanks for helping.
