windows 10 update failed, now dead computer, blank blue screen

[slinkysunshine]

I tried to roll back to previous windows 10, failed, chkdsk says no NTFS, safe mode won't load, says volume is in use by another process.  Failed to transfer logged messages to evant log with status 6.  Afraid to do full recovery, don't want to loose files, and programs I use, like Excel, Quick Books, don't want to loose pictures.  I do have many things backed up.  I am green at this, really need help.  It starts to load up to my screen picture, but it is weak and I see my log in name, but then goes to blank blue screen.  Any ideas on what I do next.  Thanks you your help!!

This issue is often due to a failing drive. So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.

If your PC is new enough to support UEFI, you can use these steps to test the hard drive: http://support.hp.com/us-en/document/c00439024

If not, to check the drive you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.
If the drive checks out OK, then report that and I can provide you options for reinstalling Windows on your PC.
