Firstly here's my config :-
Mobo: Intel DH61BEB3 mATX
CPU: Intel i3 2120
GPU: Integrated Intel HD2000 (just for testing, have a HD5450 card to use)
Tuner: Avermedia A177 Duo Hybrid PCIe
Ram: Patriot 2 x 2GB DDR3 1333 CL9
The mobo has 1 x PCIe x 16 slot, 2 x PCIe x1 slots, and 1 x PCI slot. I've installed the card in the 2nd PCIe slot (the one that is next to the PCI slot) and it stops the PC from booting into Windows. It freezes on the BIOS splash screen and at that point prevents access to the BIOS. Removing the card allows the PC to boot into Windows normally, I discovered this only after many hours of frustration trying to get the OS installed.
I've since tried the tuner card in the first PCIe slot and it works OK there (as in the PC boots into Windows OK).
There's no mention of any restrictions on which PCIe slot you can use in the doco. There's also no graphics card installed in the PCIe x 16 slot so there shouldn't be any sharing issues.
Is it likely I have a faulty PCIe slot?
Update: I took the board back to the store and they tested it with a different PCIe x1 card in both PCIe x 1 slots in turn. The board was indeed faulty as the same problem occured with their card. They didn't have any more of these boards in stock so I swapped it for another brand, shall see how I go with that one.
