Support > Boot up > Operative System failure

If we are presented with one of the following :

• After an initial start of Windows, the system hangs and nothing happens

• During the Windows loading a black screen appears saying : System stopped, restart Windows

• During the Windows loading a black screen appears saying : A file either in the registry or system.ini could not be found / loaded ( name like nav32.vdx for example )

• The following error message: VMM32.VXD: Missing/Unable to Load while Windows is loading

• The system restart by itself or a Blue screen appears

In certain versions of Windows 98, during Windows boot up the system seems to stop and with an empty screen nothing happens. If you press simultaneously the 3 buttons on the keyboard : Ctrl-Alt and Delete, a windows in the centre screen will appear and chances are there is a line of the type : Msgsvr (not responding) , well, highlight it and click on End Task button. This normally let the system carry on. The problem is related to Power management and to fix it go to : Start > Setting > Control Panel > Power Management and set all items to : Never.

Windows XP instead, will either reboot by itself or hang specially where the Windows XP logo appears.

In the cases of a black screen with the message : System stopped, restart Windows , normally indicate a system (Windows corruption) failure, with the exception of a system with an AMD Cpu faster then 350 Mhz with Windows 98 retail version One. We suggest in the first case to reload Windows, possibly from scratch and in the second case to get the patch to fix the AMD problem from the support section at Microsoft.

The other black screen issues is when a file is required by Windows but is not found, A file either in the registry or system.ini could not be found / loaded (name like nav32.vdx for example), normally is due to a program which has been recently deleted but not properly (by not using the uninstall program that came with the application or the Add/Remove in the Control Panel). In this case you will have to search and delete for the missing reference file either in the system.ini file in the Windows directory or in the registry using the Regedit program. As it is dangerous editing system files and registry, we suggest to let a trained person to do it or call us.

We found the above also occur when a mirror image of the hard drive is done from an hard drive to another without disabling the relevant application that uses the file (often an antivirus application), thus because active, Windows does not copy the file across.

The following error message: VMM32.VXD: Missing/Unable to Load normally is linked to a driver used by a UMAX scanner or similar loaded in the system.ini file (in the windows directory), to fix the problem, just edit system.ini and look for a line where there is the following: umaxis11.386 , put a semicolon (;) in front of the line and save the file, re-boot and all should be fine.

If the system starts, but at a certain point restarts by itself, means a Windows corruption. I would normally insert the original CD, reboot the PC from the CD, and when asked to repair the Windows installation press R , when at the command prompt type: CHKDSK /P wait for about 20 minutes while Windows repairs the hard disk and possibly the corrupted files. When finished, remove the CD and reboot normally Windows. Hopefully the system now works.
A blue screen and a stop message, could also mean that a driver it is either missing or faulty. In that case try restart the computer in Safe Mode, and try to see if you can login. If not you should call us.

Also, you can try to use System Restore if you are able to access somehow the desktop, this will be able to bring the working configuration you had maybe yesterday or a week ago. System Restore is found under All Programs ... System tools.
