yesterday my laptop had some problems i have windows 7 starter, some keyboard keys don't work (h,p,q,esc,backspace et.) also the Bluetooth didn't appear on window tray, so i thought some virus are in my laptop, so i decided to format and upgade to windows 7 ultimate. i installed Windows 7 ultimate with no problem but the keyboard keys still not working, wireless card is gone also bluetooth. i installed drivers
but still no luck, on device manager no wireless card is detected but i have Atheros wirelss card. any solution for this?
