I can't use "driver pack". this driver pack set a mess up data into my machine. I don't know what it installed but after restart it's hang-up. Boot is ok, Start-up also was ok, but after some time mouse poiter turn to busy or work in progree mode then nothing happen. Even Alt+Ctrl+Del is not worked at that time. Finally i have to puss the power button and reformat the machine whice was really-really-really-really borrrrrrrrrrring.
