Hi Joe,
Please contact Gateway first and confirm if your laptop is fully compatible with Windows 7. Also, confirm if there is any updated driver available for the devices.
In the meantime, go to Device Manager to see if the device drivers can be downloaded and installed from Windows Update:
1. Click the Start Button, type Device Manager in the Search bar and press "Enter". Click Continue if necessary.
2. Double click to expand the Display adapters.
3. Right click the display card and click “Update Driver Software…”
4. Repeat the above steps to update the audio driver.
Hope this helps.
