Every now and then when I install programs and when I try to open programs windows reports an error with ntvdm.exe but I have no idea on what to do about it. It's also stopping me from accessing my new Sony Vegas 7! What can I do to make this error disappear, and why am I receiving this error anyway? My computer is newly hand built and I have been getting this error with some applications ever since I booted it up. Anyone know how to get rid of it?
