My ntvdm.exe file is using almost 100% of my cpu useage and everything is running real slow and sometimes locks my computer up. Is there any quick and easy fix to this? My system is a Biostar with a 1GHz celeron processor running Windows XP and 192MB memory.

I am assuming while this is happening you are running some "heavy" applications?

I believe you can also 'kill' the process in Task Manager and it will restart itself. When it restarts itself it should be back to normal.

Thanks for the help guys, will be in touch if I mess anything up.
