Dell Inspiron 15R, continous sound of something( Driver) installing.

I had issue with laptop and found that it had some issue in chip level. the local guy got it corrected and later now i am facing continous sound of driver installing sound ( in singles), i checked in my devices, there is noting in yellow or exclamatory mark.. this sound is really annoying and its like continous, i tried restarting and many more things. 

an early support on this will be highly appreciable.

Thanks in advance
