For some reason my computer is making this whirrling noise and I don't know why. It only started this time when turning my computer on. I have hp coolsense on but don't want to turn it off as my computer might begin overheating. It comes from the top left hand corner of the second half of the laptop. I have been having problems with the laptop ever since I got it really. 5 months into having it, it started having a line across the screen and eventually just wouldn't go away so it was sent to HP under the warranty and came back fixed (though I have noticed that the sides of the screen click if pushed in gently). Every so often nowadays it will get this odd computery noise (indescribable really, it also happened today about 10 minutes ago and the whirrling noise was happening). I have had my computer since Feb 2014. The whirrling noise sometimes stops for a few seconds then comes back. It's no longer under warranty because I was not in a good financial situation when I got the popup asking me if I wanted to extend my warranty. I can provide the exact product number/name if needed. Is anybody able to help me?
