I apologize for the delay in my response. It seems you need to update the drivers for your computer. If you can access your computer, it will be easy for me to get the issue resolved.
Would you like me to remotely connect to your computer and fix the issue - The remote service will be an additional service for $30 but will allow me direct access to work on your issue and fix it (while you watch on your screen). If you need remote service, reply with the words "i want remote"If you do not need the remote service, then simply provide me the requested information above. If you need remote service reply me with the words "i want remote".
