Asus India — Camera is not working and speakers are also not working

I had been using this laptop for past 2 months and i have used it only 10 times since i brought it and suddenly speakers and camera both are not working its a matter of grief concerned and also the system is lagging behind it takes 5 minutes to open up and also we cant do multiple things at one time. in the end i would request you to take suitable action as soon as possible
