Sorry if this is a naive question - I'm not very technically adroit. My computer is running Vista 32-bit with 3 Gigs of ram. I downloaded the latest AMD/ATI Catalyst drivers for the tuner card and installed it in an open PCI Express slot, but the system does not detect the card for some reason. Even when I run detect new hardware, nothing is found. The card looks fine and all connections are firm at the expansion slot. The only possible reference I could find in system reports referred to a PCI error: IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 2, function 0. But, it also listed the error with slots 3 and 4, so not too sure it even relates to my problem. Any thoughts on this? Thanks.
