I have the Asus G73 H laptop with the ATI 5870 mob radeon, the other day I had trouble uninstalling the drivers in add/remove. So I removed them though the device manager screen and now when I install the latest drivers my card isn't being dectected!!! Windows has set to my default VGA onboard! Please help guys!
Do a clean install this time,and see if it helps
1_Download and install "Driver sweeper" from Guru3d.com and install
2_Go to add/remove programs and uninstall the driver and reboot
3_Boot to safe mode and open driver sweeper,then click on "ATI" and then click on clean
4_Reboot and boot normally to windows and install the new drivers after that you need to restart,and its done
