Hello Bedour86 and welcome to LQ,
Due to other postings of newbies using linpus, I'd recommend to install a full featured (and modern, up to date) linux-distribution. In particular if you intend to learn a bit of Linux, it will be easier to do so with another distribution.
Maybe mint is a good choice for your computer: http://linuxmint.com/
Here a link, refering to your problem, but 2 years old: http://www.linux.com/archive/forums/topic/2559
