I have a problem with ntvdm.exe running on my pc. I run windows xp and when I leave the computer running for a while ntvdm.exe starts and takes up 100% of the cpu usage. It takes a while to end the process in task manager but when I have ended the process it will be fine for an hour or so and then it starts again. Please help as it is affecting other programs as I use my pc for work. Thanks.

NTVDM.EXE is the virtual DOS "window". It runs when a DOS program is running. It sometimes uses huge amounts of CPU when it is waiting for response. If you are opening the program with a shortcut, go to the shortcut properties, then to "misc" and check the "always suspend" and set the idle sensitiviy to "High" This should stop the resource hog when in the background.

DO NOT FORMAT! "Ntvdm.exe" is a true windows 16-bit application helper. Search the file name using Google. It is possible that you have 16-bit virus running in the background though.

To solve the ntvdm.exe problem to use cpu 100%:-

1. go to start menu then select run command
2. in run command type "msconfig" then press enter
3. then select "start up" and press ok to apply it.
4. then re-start your computer.

I hope your cpu use 5 will decreases and your computer will run smoothly.

After a fresh windows xp install, I unfortunately installed "Vista Icon Pack 3.0". Before that every thing was right. after this, my computer went terribly slow, especially in start up.

after watching task Manager, I found that all my cpu performance is taken by ntvdm.exe application. I clicked "end process" and after that everything ran very very fine and CPU went from 100% to 4%.

For me, ntvdm.exe does not start automatically, but with this, my computer gets tooooooooooooo slow. If its not a virus then may be more dangerous than a virus, because it effects the PC performance more than a virus could do.

hey...i too facing with the same sort of problem. But not got any remedy for that to reduce CPU usage from 100%.
For such(Borland C or Turbo C) a kind of application,the CPU usage must not go beyong 5-10%,isn't it? . The processor has been used as if I am running a 3D game or Adobe application.
If u got ur preoblem fixed,please mail me the remedy to me to Email Id removed for security

Oh my god, it looks like a virus because you closed it down but it opened up one hour later without asking you... I recommend you to reformat your pc and put better anti virus programs and update them the more often possible!!

Good luck!!
