Ok so i have done everything as you told sir. Also i noticed that asus smartgesture was not uninstalled so i removed it as well and today used the latop without charger from 90% to 10% without issues. I'll continue using it without charger (as it is when the BSOD occurs) and will post if there were more BSODs. I'll wait and watch for a week if the problem is solved or not. Thanks for the help sir.
