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 command into Command Prompt and press Enter key.

 Dir C:\Windows\System32\config\RegBack

Above command will list files stored within RegBack folder and there file size, make sure files are not zero size if they are do not follow below instructions.

Please replace partition letter C: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.

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.

Yes you can use File Explorer (Windows Explorer) from working computer to rename and restore registry hives.

 

[Marianix]

So is this a nice solution?

 

[Marianix]

Will the problem still be there?

 

[FreeBooter]

It is like you are using System Restore tool to restore registry hives to a date where Windows were working without any problems.

 

[Marianix]

I will try that

Also my pc wont post

 

[FreeBooter]

Restoring registry hives from backup may resolve your PC boot problem.

 

[Marianix]

I mean the motherboard logo wont show up

Does the PC power on?

Does the PC power switch light is on?

Does the PC fans turning?

If the computer passes the POST, the computer may give a single beep (some computers may beep twice) as it starts and continue to boot. However, if the computer fails the POST, the computer will either not beep or generate a beep code that tells the user the source of the problem. Can you tell us if the computer generates beep code and how many they are?

 

[Marianix]

I dont hear a beep but the pc fans spin power lights on and my pc is on

Can you please reset BIOS settings by taking out CMOS battery.

How to Reset Your BIOS

 

[Marianix]

Just did and nothing happens

 

[FreeBooter]

Reset the RAM modules by reconnecting the RAM modules.
Blow off any loose dust or debris from the RAM using canned air. Hold the module by its edges.
Clean the contacts using a soft cloth that does not leave fibers behind, such as a lens cleaning cloth slightly moistened with rubbing alcohol.

 

[Marianix]

Ill try that tomorrow thx for the answer

 

[Marianix]

But it is not a guarantee fix

We don't know why your computer is not booting but it does look like its hardware problem to find out which we need to test all the computer components one at time.

You can also try below suggestions.

Reseat the memory to see if any difference. If no change-try with one stick of memory, then the other to determine which one is bad, or if both need replacing.




Please try a hard reset and see if it works.

1. Power off your laptop
2. Remove the a/c adapter, battery and everything that is attached to your laptop.
3. Hold the 'POWER 'button down on your laptop for about 15 seconds.
4. Plug in the a/c power supply (without battery) and power on.
