TV Tuner Card Driver Error in AverMedia

I am enjoying TV in my desktop pc by using an internal AverMedia TV tuner card. Last night while I was enjoying a sports event suddenly my pc shut down automatically. Immediately after that I have checked the power supply and other hardware and found nothing unusual. After then I have started the pc again and try to run the TV tuner software. But very sadly I am not getting the normal service and it shows that no TV tuner drive found. I have tried by uninstall/reinstall the software and also tried by placing the hardware into different slot of motherboard, but getting the same issue. Please help me.
