Which of the "troubleshooting" options are offered?

If "system restore" is an option, it should "time-warp" your copy of Windows back to a date/time when Windows was running normally.

This happens when Windows becomes so corrupted that it tries to redo initial setup and this will keep doing this until you get fed up and turn it off.

Also, System Restore is not, and never has been, a Time-warp feature.  You can prove that to yourself by creating a new text file and saving it.  Then do a "restore" to several days ago.  If you then check, this new file will still be there!

Your only real working option is going to be a factory reset -- using external media.

The ways to do an external factory reset are the following:
- Factory reset using external HP image you make
- Factory reset using external HP image you buy

Each of these is discussed in some detail below ...

---------- Factory reset using external HP image you make ----------
HP provides a Cloud Recovery tool that you can use, together with a 32GB USB stick, to create your on HP reset media.

This works the same as the factory reset described above.

---------- Factory reset using external HP image you buy ----------
For those PCs not supported by the Cloud Recovery, in some cases, HP offers Recover Media for sale. This can not be downloaded; instead, it must be ordered from HP.

HP Recovery Media is a set of DVDs and a CD, or USB stick, that will erase the hard drive (removing all data, settings, and applications, reinstall the original OS, drivers, and some HP Utilities.

In some cases, you may be able to order a USB stick instead of disks.

You can look online for Recovery Media starting with the linked paged: http://support.hp.com/us-en/drivers

Once there, input your Product name or number. On your Software and Drivers Download page, select your Operating System and and Version. Click &quot;Update&quot;.<br><br>If HP Recovery Media is available for your machine, down near the bottom of the page, you will see an entry for Order Recovery Media-CD/DVD/USB. Click the &quot;+&quot; symbol to expand that entry and click on Order Media for details.

Or, if you prefer, you can do the same by contacting HP Customer Support.
