It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions. Also, need to know which model Macbook Pro you have. Your system profile is a complete blank!
If you are under warranty or have Apple Care, call Apple tech support.
