My laptop was working fine untill a few days back, when I observed abnormal behaviour of the fan. When in satndby mode, with no noticeable application underway, everything is fine. But as soon as I start even my browser or Windows Media Player, the fan goes frenzy and continues to be so till I close all applications and wait for some time. The CPU usage varies between 25% and 30% during this period. The laptop does not seem to generate much heat and the exhaust of air is unrestricted. I got my laptop cleaned 2 months back. Sometimes, but very rarely, the sytem slows down but only for a short moment.
Please help.
Thank You
