Welcome!

When you say "and isn't", could you give some idea of why you are unable to reinstall the device?

There is nothing in your post that gives anyone here a hint as to what the actual problem is, in order to offer help.

You indicate that you have a Compaq Presario, however that covers several hundred different computers, you may need to offer a computer model number or at least the version of Windows you are using.
