i had this laptop since summer of 2013 and its been working fine and still is. recently when i turn on my laptop the top right part ( if placed like a normal laptop) on the back has this really really loud sound coming from it. at first when i turn my laptop on it starts and stops after a few times of that it just stays on. When i turn off my laptop the noise gradually slows down so im thinking its the fan. I took the back off and used caned air to clean the dust but the noise is still there any suggestions?
