I just bought an AMD Theater HD 750 TV Tuner PCIe Card for my PC. When I install the drivers my wired internet stops being able to connect. And when i try to run the troubleshooting diagnostics it gets to resolving problems, then my computer freezes. I did system restore and it was working again, went through the same steps and got the same problem? Any ideas. The tuner card is supposed to work with my PC. Thanks for any help!
