This product was either defective or was severely not compatible with my computer. From the moment it was installed my operating system started with error messages. I had a message that my version of windows was not genuine and it tried to shut down every time I tried to open a program. I took the module out and everyting was normal again. I think I am going to replace it with a different brand.
