I suspect that my motherboard is bad, and that my PCI-E slot is not working.
I have a Gigabyte motherboard that had a Hauppage 2250 working fine in the PCI-E slot for many months.
However - recently - would not get TV channels that I used to get --- until finally Media center cant detect any channels at all. Got a new tuner card (ATI 350 card) - cant detect any channels. The cable signal is good - I have it connected directly to a TV - all channels come in clear.
SO that is why I suspect a motherboard problem. Are there any motherboard diagnostic scanner utilities that can verify I need a new motherboard>
3As this only indirectly answers your question, I'm throwing it up as a comment. Are you using an antenna with the tuners? If so, the transition to digital broadcasting could be the culprit. Some newer TVs are equipped with converters built-in, but TV tuners such as the Hauppage 2250 may not be equipped to automatically convert the analog broadcasts. – Emory Bell – 2009-12-27T23:34:21.810
