Hello, my computer keeps freezing. Some times I can login but, sometimes it freezes before i login. When I do login, it freezes 1-5 minutes after i run a program. The weird thing is, it will freeze but, I stll can move the mouse(but i cant click with the mouse) and the clock at the bottom right still works. It seems like my computer is still running but i cant control anything on it. For example, I was playing toribash and it froze, i could still see people chatting and playing the game but, I could not type, click, ect.
Well, I hope someone can help me.

EDIT: The only info i could get is on this page http://www.amazon.com/900HA-8-9-Inch...outThisProduct

Thank you.
But what is OS? sorry im not very computer smart.
