According to your description, I suggest you refer to the following information:

The bar keeps turning and making abnormal noises.

Before the end of the problem: 14 days and 3 hours.

Yesterday, I didn't brush the global display on the internet, and the screen suddenly turned white, and the two water ripples on the upper right kept moving. ...

1. Regarding the screen problem of your machine, I suggest you use an external monitor to confirm it. After switching screens, if the external monitor displays normally, it is generally a notebook screen problem. If the external monitor also has this situation, it may be a problem with the graphics card or motherboard. The specific situation requires further testing and judgment by the on-site engineers of HP Gold Service Center.

2. Please confirm the maintenance price and the required documents to the maintenance center.

You can check the nearest HP Gold Service Center through the following website:

I hope the above reply can help you.
