NTVDM Illegal Instruction



I am receiveing the following message whenever I try to install a new game or
at other seemingly random times:

The NTVDM CPU has encountered an illegal instruction.
CS:d3of IP:0134 OP:f0 a2 4e e1 10 Choose 'Close' to terminate the application.

Any advice?

My system is Windows XP Professional

Run the System File Checker, you may have a screwed up file.

System File Checker (sfc.exe) replaces screwed up system files.

Load your XP CD in your CD drive.

Start | Run | Type or paste: sfc /scannow | Click OK

sfc /scannow scans all protected system files immediately and replaces
incorrect versions with correct Microsoft versions.

System File Checker takes a while to run.

If you have XP Home and it asks for your XP Pro CD, see this KB article...

You may be prompted to insert a Windows XP Professional CD when you run the
System File Checker tool in Windows XP Home Edition

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

Open the Event Viewer...
Start | Run | Type: eventvwr | Click OK | Click System |

Windows File Protection will be listed under the Source column. Look at any
Windows File Protection entries.

Explains a whole bunch about sfc.exe.
scannow sfc (sfc.exe)
