I'm not very good with Ubuntu as I'm a newbie user.

From the switch over from 10.10 to Natty my computer has decided to hate me.

It constantly freezes up and I'm forced to restart my computer all the time. ( Usually a few times per day )

The computer also freezes up if allowed to go into hibernate mode / sleep mode

I also have a problem with connecting and staying connected to my university wireless internet connection

What information do I need to give and how do I give it to you all?

(I can work the terminal)
