I have a whole new issue with my Asus N73J -laptop. It started today and has done it now 3 times. It occurs when i have few windows opened and couple softwares like Skype running. So, me screen suddenly freezes, mouse doesnt move etc. If I have my skype call opened, like i once had, it suddenly ends. Only way to get out of this problem is, to reboot the computer and it works again. Please help such a newbie like me..
