[ubuntu] kernal panic help

view story

http://ubuntuforums.org – So, im a complete beginner here, and well my ubuntu constantly has kernel panics. At least, thats what i think it's doing. it freezes up responds to nothing, and the caps lock is blinking. this happens every once in a while randomly, but especially when i am running something along with the internet, or if i leave it untouched for some time. it also does it randomly too. i've read threads that tell me it's a wireless driver issue, and that changing drivers fixed it, but I'm not too sure if thats my problem right now. I'm running ubuntu on a hp pavilion btw. any help in simple language would be greatly appreciated. :) (Hardware)
