I helped a fellow with the The NTVDM CPU has encountered an illegal
instruction error and running system File Checker fixed the problem for him.

Click Start | Click Run | Paste this in the Run box...

sfc /scannow

Then click OK.

It should take a while to run.

If SFC.EXE did anything it will be in the Event Viewer.

Open the Event Viewer...
Start | Run | Type: eventvwr | Click OK |
Click System | Look at any Windows File Protection
entries

Not everything in the following article will apply. The article was written
for Windows 2000. However most of it does.
[[If it was not one of those, you can try the DLLs under the following
registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\W

Value: Known DLLs]]

The above should read...
