have the same problem like here : http://social.answers.microsoft.com/Forums/en-US/vistaperformance/thread/2914698d-fea5-4a53-860e-585b327dfe42 tried the stuff that writing there and it didnt help it occur for the first time after an update of microsoft for SQL Framework pack (something like that). Thank you all for your time and help I have an annoying problen with a DOS window that pops up every couple of seconds. It was really hard to catch, but reads "The Syntax of the Command is Incorrect" and is in C:\WINDOWS\SYSTEM32\CMD.EXE. I thought it had to do with a NVIDEA Unified Video Graphics update, but maybe not. It started occuring a month or so ago (maybe after doing this update). After a week or so, it seemed to make sense to try going back to the original driver. That seemed to be the solution and all was well for about 10 days. Yesterday it started again with a vengeance (every 3 or 4 seconds) 1 person needs an answerI do too
