if you are pretty comportable with playing around with your laptop, just open it up and take your fan out
you will see why
i was like
when i took out the fan, i just thot its sponge or some kinda material installed from factory
but, soon, i realize its not something from factory
before i clean those out, temp from i8kfangui was....
idle CPU 62 // GPU 61 // memory 57
high load (i ran Company of heroes less then 5min)...
samething happened to me
it just stopped working one day
tried reinstall driver few times.. no go..
not a big deal.. so i used USB to my phones, camera, and PDA
i had to reinstall windows, so i did
it works now
but one thing..
whenever i install this 9291, LCD did not display anything from 'welcome' screen first 2~3 times when i reboot
had to use windows key and 'u' 'u' to turn off my laptop on black screen
other than that.. nothing so far.. it was just first 2~3 times after i installed
think 9291 caused it.. not sure tho :P
