Hi akramul, It's depend on the configuration of your laptop plus how many times you have formatted your laptop before. Formatting your laptop for a lot of time decrease the speed of your laptop because it directly affect your motherboard system. So try to format only when needed the most. I will suggest you to take your laptop to the nearest dealer and tell your problem. Will sure you will get your solution. So best of Luck.
