As with the advancement in the technology I have switched myself from desktop to Dell Inspiron 6400 laptop. I have installed windows 7 operating system with the latest drivers and updates for my hardware devices and software applications. All the things were going fine. While surfing the internet last night I am getting the error code 28 and my system freezes. Due to this error code I am facing problems. Also I am unaware of this error code and need a solution so that I can resolve from this problem.
