how and where can i download sound card driver for my notebook asus?

At the manufactures web site of your computer, that's where I download mine.

If it really is no longer below assure, open it up and seem to verify no longer something is free close to the fan. Spin the fan along with your finger and verify it really is free and is no longer touching something. The fan grinding should be the reason behind your extreme temps. the clicking sound should be your HDD. If the clicking isn't loud and very speedy, then it truly is likely prevalent. If even if, it really is a noisy rhythmic click, then you definitely have issues! if so again up your records and replace your HDD once accessible!

go to http://www.asus.com/ and you can search for your notebook and download the dirver needed!
