Can you reply with the model number of your graphics controller and the graphics driver version?
Thank you for your reply.
Not 100% sure which one is the controller so I'll list the relevant bits from system info.
Driver Version: 184.108.40.2068
Accelerator: Mobile Intel 4 Series Express Chipset Family
Processor: Intel 64 Family 6 Model 23 Stepping 10
Please let me know if that doesn't cover it and many thanks for the help!
