Hello Aniket_3, welcome to Daniweb!
To start with, could you please provide us with more specific details regarding your hardware specs?
Since you indicated that you were installing driver updates when the problem occured, giving us exact information about your hardware components could help us track down what went wrong during the update process.
Also: if you happened to catch the name of any of the drivers that were trying to install themselves, that would helpful as well.
