Hello kamah. Welcome to the Forum.

I took a look and found that the error message can be associated with at least 2 conditions:

• You have an old game or program installed that is incompatible with W7.
• You have malware on your machine that has added unneeded .com files

Diagnostic for #1: The NTVDM CPU has encountered an illegal instruction. - Microsoft Answers


Diagnostic for #2: run a good antivirus/anti-malware scan.


See if that helps
