My certified data laptop quit all of a sudden and turning it off and on or even removing the battery does not help it just goes to safe mode or open windows normal and the screen stays blank

Symptoms seem to indicate either corrupted or missing driver files (probably other corrupted files on hard drive as well).

You can boot into Safe Mode, then run Command Prompt, and type the following to try to correct corruption on the hard drive:
chkdsk c: /r

You will get a message telling you the drive is in use, and would you like to run on next restart. Type "Y" and hit enter, then restart the computer. Depending on the size of your hard drive, this could take hours to run, but be patient.

If this does not resolve your problem, the next thing to try is (in Command Prompt again) "sfc /scannow". You will need your installation disks as this program does a full System File Check and will ask for your installer CD/DVD to replace any missing or corrupt System files it finds.

I hope this helps...

  1. Download the mscomctl.ocx file to your desktop (right-click on link and choose 'Save link as...')
  2. Then go to My Computer > C: > WINDOWS > SYSTEM folder to check if you have a previous version of the mscomctl.ocx file. If yes, just make a backup of it.

After replacing the file, you will need to register the newly downloaded file. To do, follow the simple following steps.

  1. Click on 'Start' button and click on 'Run'
  2. In the 'Open' line, type : regsvr32 \windows\system32\MSCOMCTL.OCX
This command will register the file you have downloaded and added to the SYSTEM folder. You should see a message saying "DllRegisterServer ... succeeded" if registration is OK.

It doesnt want to start it says what im describeing.


This behavior can occur if the Windows\System folder is missing or renamed, or if the PATH line in the Autoexec.bat file is missing or does not include the Windows\System folder.

To resolve this behavior, use the appropriate method:

Method 1 loadTOCNode(2, 'resolution');
  1. At the command prompt, type: dir vmm32.vxd /s If the Vmm32.vxd file is not found, you must install Windows 95 or Windows 98 again. If the Vmm32.vxd file is found, note the folder in which it is located, and then continue with step 2.

  2. At the command prompt, type the following commands, pressing ENTER after each command cd windows
    ren folder system
    where folder is the folder you noted in step 1.

  3. Restart your computer.

Method 2 loadTOCNode(2, 'resolution'); Using a text editor (such as Notepad), edit the Autoexec.bat file and add or modify the PATH line so that it includes the Windows\System folder. For example, add the following line to your Autoexec.bat file: path=c:\windows\system

Hope this helps,

Ntldr is missing press clt alt del to restart

The NTLDR and files are important system files that are used by your computer to start the Windows XP operating system. These files can become damaged, corrupted or deleted for a number of reasons and are usually brought to your attention by the "NTLDR is Missing" error message. 

Follow these easy steps to restore the damaged/corrupted or missing NTLDR and files from the Windows XP CD using the Recovery Console. 

Time Required: Restoring the NTLDR and files from the Windows XP CD usually takes less than 15 minutes

Here's How:

Boot your system  using a Windows XP CD, press any key when the windows display "press any key to boot from CD"and wait for some time, select "r" option to go to recovery console. it will ask you for administrator password too.

When you reach the command prompt type the following two commands, pressing Enter after each one: 
copy d:\i386\ntldr c:\
copy d:\i386\ c:\

In the command listed above, d represents the drive letter assigned to the optical drive that your Windows XP CD is currently in. While this is most often d, your system could assign a different letter. Also, c:\ represents the root folder of the partition that Windows XP is currently installed on. Again, this is most often the case but your system could be different. 

If you're prompted to overwrite either of the two files, press Y. 

Take out the Windows XP CD, type exit and then press Enter to restart your PC. 

Assuming that missing or corrupt versions of the NTLDR and/or files were your only issues, Windows XP should now start normally.

That's it.

Missing or corrupted file C:\windows\himem.sys

If you are running Windows 95, Windows 98, type:
copy himem.sys c:\windows <press enter>
If when typing any of the above commands you receive a prompt that the file already exists, ensure to overwrite it.
Reboot the computer; if the issue continues to occur, verify that the config.sys is properly setup. The line himem.sys should read:
Additional information and examples of the config.sys can be found on our autoexec.bat / config.sys page.
