Greetings,

Welcome to the forum.

I am not a HP employee.

This error can be checked at this site (Link). Carefully read all tips at this site to possibly fix the problem.

You have the following possible causes:

1. Hardware

2. Device drivers or system service

3. BIOS incompatibility issue

4. Wild card, a Windows update has a problem with old hardware or old hardware driver

You know you will lose data if you reinstall Windows.

Check hardware. Start the PC. Tap "F2". Run system tests. A hardware pass suggests you have a different problem.

Try Safe Mode by starting the PC two or three times. Then shut down after each startup and before the blue screen occurs by using the power button to shut down.

This should load safe mode. A good safe mode startup suggest you have a driver or system file problem. You could use Device Manager to uninstall hardware drivers. It is anybody's guess which driver is causing the problem.

Also try running System file checker commands available at this site (Link).

I don't know how deep you want to go.

You can't deal with a possible BIOS problem if you can't run Windows on most HP Desktop PCs. BIOS updates must be done when Windows is running.

Sometimes you must bite the bullet and do a clean install to isolate a hardware problem. So again, you will lose data unless you pull the OS drive and connect it to a different PC for data retrieval before you install Windows on this HDD again.
