|What model of TV card is it ? |
If it has an ATI chipset I am familiar with those.
A software problem will not cause the PCI TV card to not be recognized, unless the drivers for the card's TV tuner were corrupted or were not installed properly.
"The PC sould recognize any card being installed..."
DO NOT plug the PCI card into the last of the PCI slots closest to the center of the mboard. That PCI slot usually shares it's IRQ with the onboard video or the card in the dedicated video slot's video, and in that case any card except a PCI video card is likely to not work properly in that slot.
If you look in the mboard manual for the model, the info about which slots share an IRQ with what is usually in that.
"installing and reinstalling drivers accomplishes nothing. "
TV card "drivers" always have associated files that must be installed properly along with the actual drivers. If you install only the actual drivers, it's likely the device will NOT work properly.
When you install the software for the TV card, you must do that the proper way.
Unless the instructions for installing a device tell you otherwise......
(this ALWAYS applies to TV card software.....) .
You DO NOT install drivers for a device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.
The same applies no matter when Windows finds New Hardware !
(The following also applies if you want to re-install the software)
If you DID install drivers that way, go to Control Panel - Classic View - Programs and Features and Un-install the software you installed, reboot, DO NOT install drivers while booting, or when New Hardware pops up at any time.
Continue on to the desktop screen, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.
