run dll error

i have this error i dunno where it came from ? i dunno what happened and what program cuzed it every time i start my pc now it appears at the beginning i attached a picture of the error appreciate any help

Try this...
1) In MSCONFIG, click on Startup tab, then scrutinize the entries. Disable anything that may seem connected to the problem.

2) Download and run CCleaner, do both a regular cleanup as well as a registry cleanup.

3) If the above 2 steps dont solve the problem , try reinstalling the .NET framework

thank you

the MSCONFIG worked i tried cccleaner and windows 7 manager they both didnt do any thing in the MSCONFG i found that line in the attached picture
the start up item is MSSMSGS
the manufacturer unknown the command & location in the attachment
