So I was just on my computer and all of a sudden it froze. I couldn't do anything with it so my only option was to press the power button. After did that I turned it back on and an hp logo popped up and under it is a loading sign. I took the battery out of the computer and I keep turning it on and off.nothing is working. Sometimes when turn it on it will say something like "preparing automatic prepare", and then it goes to "diagnosing your pc". I'm not very smart with computers so I would really appreciate it if anyone could help me. Thanks.
