Hi Sir Another fix you could try is looking in your device manager and checking what keyboard device is registered if it says that you are using a ps2 then you need to uninstall the device and then close the device manger after which you should unplug your key board and restart your computer when you hear the bleep reconnect the keyboard into your USB port and see if this works if not you need to check if you have enough power to your keyboard from your USB port as some USB keyboards need power is your USB port 2.0 if not try to upgrade your USB to 2.0 from the usual 1.1 ports Hope this helps Paddy

If you have disks supplied with the system, they normally offer more than one type of reinstallation; destructive and non-destructive.
In most cases, neither of these will absolutely remove all traces of former files.
If that is what you wish, you can reformat the hard drive and remove the existing directory and make old files unaccessible except to experts wanting to 'get the goods' on someone.
There is also the chance to backdate the system to an earlier time in case something has bollixed enough files to make it unstable. That procedure is called 'restoration' which replaces the system files as they were at an earlier time so corrupt files are replaced with fresh copies from a separate partition on the drive. This method leaves your personally created files intact if that is desired.
These various possiblities depend somewhat on the version of Windows you are using and information in the Windows Help section can give you guidance if you want it.
If you have sensitive information that you do not want anyone to ever access, there are numerous freeware programs that will overwrite existing files so completely that even experts cannot recover them. They use various methods of trashing files but most offer the chance to set how many times you want them overwritten and by which method, among these is using all zeros or random numbers. Finally, the last option is to replace the hard drive with a new one, physically disassemble and destroy the disks mechanically although disposal would still be sensitive since there are methods of reading file segments on even catastrophically damaged disks.

It seems that you have Dell Desktop computer, unless you requested a wireless card to be put into the computer, it would not come with one. Just like stang_1 mentioned, you should check your network adapters to see if your wireless card is listed. Also since it is a desktop, you can check the back of it to see if you have an Antenna sticking out of it. That would indicate that you have a wireless card on the PCI slot. And if that is the case and you do not see it listed in the network connections, check the Device Manager and make sure that the drivers are installed properly.
