Why does it sound like bad bearings when I start my car? Please help need her fixed

What is your question?

When I start my car it sounds like bad bearings under my hood then it goes away and rides fine with no noises. Got a new alternator,starter,battery and tensioner and pulley within last 2 weeks. This is a new noise. It'll make a noise for like 5 seconds at start up then stop. On way home today she was making a whirly noise and it was her tensioner so fixed that and now it making this new noise. She started acting up about 2 weeks ago and that was the alternator bad in her, yes I had it tested. Then I got a new battery because this old one was ready to be replaced kept on having to have it recharged. Other day she got a new starter, yes that was also tested. And today a new tensioner arm and pulley.

What makes this problem better or worse?

Nothing
