Other problems I had with this notebook started a month or two ago. 

I purchased this HP 2000 Notebook PC Windows 8 64-bit new in 2014. 

Fixed some problems by restore, refresh and refresh again. 

A week or two after purchase I upgraded to 8.1, then I put it on Install Updates Automatically for Windows = just found out 3 weeks ago no Windows update from 2014 to 2019. 

Task Manager Memory 72% = fixed = deleted HP Connected Remote Service memory. 

Task Manager Disk 100%

Error 0x80070490

Error 0x80070057

Can not open windows update. 

I’ve been trying to fix problems for 2 or 3 weeks. 

May of been other problems don’t remember. I need to start a PC Problem Diary.

I’m getting tired of trying to fix pc problems. 

Thanks for any info you can give me.

And what happened when you followed the advice at the link that was at the HP link you posted?

That link I gave you from your link is not the diagnostics.

It is what you do to ascertain what has gone wrong.
