My company just bought a CQ40-324TU for me. Is it freedos, so I installed win xp on this laptop, every driver is ok except UAA driver and sound driver, When I installed sound driver, then it is functioning. But after I reboot my laptop, sound driver missing and I need to update UAA driver 1st and new hardware found, then I install sound driver again. Anyone can help me on this problem?Thanks in advance.
