Vmm32.vxd missing...

Hi all,
This is a problem I've been encountering a lot lately...
People boot their PCs with Win98 and their machine powers down at the windows splash screen - when trying to access safe mode it hangs at the splash screen indefinetly with the hard drive continually grating. With step by step confirmation it says that the file
c:\windows\system\vmm32.vxd is missing

I've read the Microsoft support article on this problem here - http://support.microsoft.com/support/kb/articles/Q191/8/74.ASP

This article seems to indicate that a scanner causes the problem but in not one of these cases is a scanner involved. We do not have a solution to this problem and it seems to happen at random and for no apparent reason. Eg - it happened recently after someone just cleared the CMOS!
In every situation we have had to recover the PCs involved...

Does anyone have any information on how to fix this problem - or even better - what causes it and how to prevent it?

Thanks
Cathal

I know you said a scanner is not involved but look in your system.ini file for any reference to "Umaxis11.386 "  if so, rem it out.

<< with the hard drive continually grating.

To me it sounds like your hard drives are flakey.

I would recommend that you download a diagnostic disk from your harddrive manufacturer's url. This will tell you right off where you are at and if
   you can recover from it. It may be under waranty, the harddrives are usually covered for three years and you can make out the RMA on their site
                     also. Depending on the manufacturer of the hard drive, you can download diagnostic utilities from their sites to check the drives.

Churning from searching and not finding, perhaps also churning because of a badly fragmented swapfile and hard disk that scandisk/defrag may help.
