Likewise, I've used Kingston in my own personal Toshiba laptop and it works fine as well. You shouldn't have to do anything other than install the memory. You do want to make sure it's seated properly but that's it. Reinstalling Windows won't solve any memory problems but rather it will create other problems with your software. Windows doesn't need to recognize memory, the system itself does. Where was this phone tech from?
