when starting my system I get an error message:
c:\windows\system\vmm32.vxd not found. The file is
located in c:\windows\system\.. when I reboot and
select step-by-step dialog. I get as far as:
c:\windows\system\umaxis11.386.exe not found. Thisalso is found where stated. Occasionally, my
desktop icons become scrambled?? I can use the
computer after single stepping but when shutdown I
get the same errors. Registry????

At command prompt,type:

dir vmm32.vxd /s

If not found reinstall the operating system,if found note folder in which it is located

At command prompt,type the following commands,press enter after each command

cd windows
ren folder system
where folder is the folder found from search

In windows 98 or ME you have the system file checker to check for corrupt or missing files,it can be accessed thru System Information from the Accessories menu

Followed this procedure and found that the files were listed
where they were listed in the error message.
c:\windows\system\vmm32.vxd and c:\windows\system32\vmm32.vxd.
Still comes up as an error on startup.

This erratic behaviour is caused by fault during installation of drivers. In this case, the most appropriate is the installation of UMAX scanner driver.

Otherwise it might also be caused by VGA driver. Try to uninstall both, for UMAX using the uninstallation application, while for VGA you could use Device Manager.

After that, try to reinstall again one by one.

Keep me posted.

I had a computer with similar simptoms.
I suggest you to use for all <*.exe> on your HDD. If you find some strange exe files, with letters and numbers in name then your system is infected with Klez virus. Also you can use from Symantec to check your computer (download on other system and put it on a diskette and run from diskette).

Has the hard disk been in service for a long time? Or is it past it's MTBF (Mean Time Between Failures) rating?
You might be able to run Scandiskw.exe with the surface scan enabled to test the HD. If there are large number of unusable sectors (Marked with red) then the drive may be near failure...

Vmm32.vxd is Microsoft's Virtual Memory Manager. Rename the Autoexec.bat and Config.sys to Autoexec.org and Config.org respectfully, and reboot. This will allow Windows to load its Himem.sys and Emm386.exe, thereby utilize all of its memory allocation.

The error concerning Umaxis11.386 is a misnomer. Windows only has so many error messages, and I find that it will often list a file as not being found when it just can't load the file into memory.

If this it the case - you can either createDOS properties in the Icon shortcut(s) for the needed Autoexec.bat and/or Config.sys commands, OR load the Himem.sys and Emm386.exe up in the system startup files. The first is a better solution than the latter.
