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>
