Thanks guys for all the info here,never know that this particular laptop got it own fan.... =)

I myself had already use K40AB for almost 4 months right now,from XP to Vista and now i'm using Win7 Ultimate 32x.

And for the 1st time i got this gpu driver for HD 4570 problem,i already try the driver given from Asus and also AMD but STILL when i check in device manager its say "This device cannot start. (Code 10)".

Please if anybody could help me for this small matter but very frustrating...

TQ in advanced..
