Fix Dell Studio XPS Laptop Hanging Problem

Symptoms

Everytime you want to view a flash video (from Youtube, CollegeHumour and others), your browser will stop responding. Changing to other browser or updating Adobe Flash wouldn’t work.
Using Google Talk in Gmail will also make your browser hang.
Google Talk (Windows Edition) would also hang after you started chatting with someone. You can’t also connect back to Google after relaunching it unless you restart your computer.
Your volume panel (the one that pops out when you click the speaker icon at the right corner of your desktop) will hang when you want to change your volume level.
Skype would also hang and wouldn’t connect back after you’ve restarted the program and the only way you can connect back is by restarting your laptop.

Cause

Most probably because of the sound driver. No one can confirms it yet.
