TV tuner card messing with my pc

[rumjudge]

I have purchased and installed the PixelView PlayTV MPEG2 tuner card over a month ago and I have had problem. It has slowed down my computer when I'm playing games. The game play is horribly choppy and slow. I have tried to removing the card and uninstall the programs that came with it and it did not help. I've tried adjusting the setting of the games and the video card and that too has failed. I have also tried moving the card to different pci slots which didn't work. I am very happy other wise with the performance of the card. I would appreciate any help anyone can give me. I am listing a detailed list of my computer system.

It might have messed up your video card drivers. Remove any video card related software/drivers from add/remove programs. Then Use a free driver cleaner to remove anything left behind. Then reinstall the latest video card drivers and see if that helps.
