Hello Michael, I’m sorry for the inconvenience that you have faced with your system.
It is very important to understand that that we try to make our products compatible to many third party components as possible, but we cannot always guarantee compatibility with all of them.
The recommendations I can give you are to make sure you have the latest BIOS and driver version available installed on your system. Also make sure you have the latest firmware of the TV card.
You can also test another PCI device on the board, in order to find out if you have the same behavior.
