Hi Basim Sulthan,
It seems the display drivers installed on the system are for Windows Vista. However, currently you are using Windows 7 x64. I would suggest you to uninstall the display drivers from the device manager and re install current drivers.
To uninstall the driver, you may follow the steps below:
- Press ‘Windows’ key + R on ‘Desktop’ screen
- Type ‘devmgmt.msc’ in run box and press ‘Enter’
- Click > sign next to ‘Display Adapters’
- Right click the entry listed under ‘Display Adapters’ and click ‘Uninstall’
- Click ‘Yes’ on the security warning
To re install display drivers please visit the link: http://dell.to/109rLp9. Click ‘Download File’ and follow the on screen instructions.
Hope this helps. Please reply if you have any other questions.
