So one day i was watching movie, when my computer got really loud. It happens sometimes when i play computer games.
I restarted it and it was quiet again but when it gets a little hit it get's loud again.
Its not overheating, so i dont know what is wrong with it. I have that fan or i dunno how you call it.

Computer is Laptop Packard Bell EasyNote TV.

Sorry for english 🙁

A tad confused here. Are you saying it got 'hit' or it gets 'hot'? Assuming you mean hit since you say it isn't overheating. However a fan will get loud when something is overheating. Hence the confusion. So, is it hot or hit?
