RunDLL and NTVDM CPU Error

When I try to open some of my programs and applications I get a blank window with (C:WINDOWSSystem32rundll32.exe) in the header. Another small window opens inside the other window with. (16 bit MS-DOS Subsystem) in the header with the error message. The NTVDM CPU has encountered an illegal instruction. cs: 0dad IP:0195 OP:63 d7 3b 6c ee choose “close” to terminate the application. The first set of #’s and letters, “0dad” change, 0db6 is one of the other series of #’s and letters that has appeared. I have tried buying RegCure to help fix it and I already had Bit Defender 2009 installed. I have also lost my whole E: drive is now missing and I am in severe need of memory, system restore is inoperable now but I tried it when it was working and it did not fix the problem. I’m not sure when I started having problems, but I think it was around when I installed the update 3.0,3.1, service pack, but I can’t get into Add and Remove Programs. When I open system info, I get a blank screen. Please help. I’m worried about my hard drive and its data.NTVDM CPU Error, rundll error, illegal operation

I know that Kate addressed this question in her answer to the post on July 13^th. Did you try Windows System Configuration or to repair Windows and those didn’t work for you? If you haven’t tried them, my first suggestion would be to go back and follow the step-by-step instructions to see if that solves your problem.

DLL Errors

DLL files are small files that are part of the operating system of a Windows computer. They provide a function for a specific operation for several programs. There are ways to get rid of DLL errors manually, but because this can seriously damage your computer if done incorrectly, I never give directions for removing them yourself. I’m surprised that RegCure didn’t work for you - if you didn’t have success with the program then I doubt that a tech will be able to do it manually.

NTVDM.EXE Error

The ntvdm.exe is another matter. This happens when you are trying to run a 16-bit program in a 32-bit environment. Have you installed anything new lately that you can easily remove? It can also be caused by malware, which can be a problem if you can’t access your antivirus programs.

We don’t offer direct support here, but we do recommend an online support company which you might want to try before you resort to reinstalling your operating system.

Hard Drive Data

If all else fails, you should still be able to get the data off of your hard drive - even though you are experiencing several different problems, hard drive problems don’t appear to be one of them. If you don’t have your data backed up, you can still pull the hard drive and copy it over either as a slave in another PC or by using an enclosure. Once you have your data copied, you can load your Windows CD and choose to install a fresh version of your operating system. Be aware that if you suspect that the cause is malware, anything you back up may be infected, so it might be wise to back up the bare minimum that you need and make sure you run a good antimalware program right after you install the new operating system.

Try some of the suggestions and see if you can get your system up and running. If that doesn’t work, you may want to get some technical help to back up your hard drive and reinstall Windows.
