I am simply getting a constant problem here. I am facing some problem with NTVDM cpu here. When I try to use my pc I am getting a problem that the cpu encountered illegal instruction error. I am not able to find any solution here. I tried everything but nothing worked. I am trying to run windows xp on my home pc but the problem here is simply different. It looks like some kind of very serious issue to me. Can anyone here guide me to deal with the issue. I hope there will be some option available through which I can fix the issue.
