Did you ever run Windows 8 on the system before the SSD?
If you have a network adapter, you might check to make sure the driver is identifying it correctly, and try adjusting the Power Management in its properties in Device Manager. I just say this because Windows 8 gave me problems with my Ethernet adapter, so it might be similar to your situation.
If you have any more info, someone might notice other things. Any log entries in Event Viewer?
