Re: very very and i mean very
Phir theek hai.. rehnay do.. koi aur wajah hai..
That’ll be the thing to do, if you cant find the culprit behind this..
but I suggest you dont do this yourself, as you dont know what it is 
Ask someone from your friends/families to help you re-install windows, mind you, you will lose everything by doing so, iss liyay make a backup of all your important files on CD/DVD.
