HP Desktop

 

Good Old Wins 7 logo with flag comes on

 

Stays there for 30 secs, then goes off

 

Screen black, then mouse appears on black background - then restarts

 

Safe Mode No good

 

Booted from another disk - repair - no good - chkdsk /r - no bad sectors

 

System Restore took it back in time, but no change - now there are no other restore points to choose or UNDO

 

sfc /scannow (offbootdir....) did not find integrity violations.....

 

Last Known Good Config - no good

 

Bootrec.exe /fixmbr & /fixboot - no good

 

Pressing F8 on start does not bring up "Repair This Computer", only Safe Mode etc ???

 

============

 

It has Norton - just wondered if I could get into it to stop Norton, or other things trying to load in case it is that ???

 

Any other ideas welcome !!!!

Windows Vista/ 7/8/8.1/10 keep a regular backup of the registry handy in case you need to overwrite a corrupted registry. By default, the RegIdleBackup task runs every 10 days, so that’s as far back as you would lose if you replaced the current registry with the automatically backed-up files. You can find the backed-up registry files in \Windows\System32\config\RegBack folder.

Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

Please type below commands into Command Prompt and for each command you have typed press Enter key.
 

Ren  C:\windows\system32\config\SAM         SAM.BAK

Ren  C:\windows\system32\config\SYSTEM      SYSTEM.BAK

Ren  C:\windows\system32\config\SECURITY    SECURITY.BAK

Ren  C:\windows\system32\config\DEFAULT     DEFAULT.BAK

Ren  C:\windows\system32\config\SOFTWARE    SOFTWARE.BAK
 

Copy  C:\Windows\System32\config\RegBack\SAM         C:\windows\system32\config

Copy  C:\Windows\System32\config\RegBack\SYSTEM      C:\windows\system32\config

Copy  C:\Windows\System32\config\RegBack\SECURITY    C:\windows\system32\config

Copy  C:\Windows\System32\config\RegBack\DEFAULT     C:\windows\system32\config

Copy  C:\Windows\System32\config\RegBack\SOFTWARE    C:\windows\system32\config

This procedure assumes that Windows Vista/7/8/8.1/10 is installed to the C:\ partition. Make sure to replace C:\ drive letter to the appropriate Windows OS installed partition drive letter if it is a different location.

Above commands renames the registry files at their existing location, and then copies the registry files from the RegBack folder to the C:\Windows\System32\Config folder.

 

If replacing registry hives won't resolve the issue you can uninstall Norton driver follow the instructions at below link.

If the system used to work properly what do you think happened to it since the last time it did work properly?

 

It it restarts you should choose from the F8 Advanced Boot Options menu:

Then if you have a STOP error (or something else) tell us what the entire STOP message says as indicated in this example:

The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates.
