As it is today I have Win Xp sp3,but what I´ve discovered is that some of the registry files are corrupt; can´t find some Dll-files (at the regular starup process). The hardware is as old as the computer(both the graphic RAM,HDD etc).

Please share the troubleshooting steps performed by you. You may check in ‘Device Manager’ if the wireless card is detected or not and if detected is there any exclamation mark, question mark or red X on wireless card. Please follow the steps below:

I need to find out how to disable the touch pad for my Inspiron N5030. The problem is that it does NOT show up as any listed hardware device, so it can't be shut off. I can find nothing on here that shows that it even exists, and the hot key for it doesn't work either.
