I have a problem. recently i have downloaded the ubuntu 14.04 LTS 32bit operating system.
Installed along side my windows operating system, so half for windows and half for ubuntu

My system is "HP Touchsmart IQ500uk"

the problem occurs when i boot into ubuntu, It boots up fine. but within 2-3 mins of the operating system up and running. the system hangs.
I cant move the mouse cursor neither can i use any combination of keys.

Can some one advice me on what i can do to resolve this problem. i would love to get ubuntu working on this system

Please note i dont know my way around bash commands. so im limited to my knowledge

thanks for any help given
