I understand you have issues installing PCI Express TV tuner card.
Onboard graphics solution is disabled electronically when you install a video card on the PCI Express slot; this is because the port was designed for graphics only.
I recommend checking with your TV tuner manufacturer for compatibility information.
Also, check with your computer manufacturer for troubleshooting information about PCI Express issues.
Thanks Allan. Just to restate clearly - the TV tuner card I have is not a graphics card (e.g. it does not include a display port or video chipset - when working properly it should leverage the onboard integrated Q45 graphics.) - and it works fine with other similar chipsets.
When you say the PCI express port was "designed for graphics only" - does that mean that I should not expect other types of PCI Express adapters to work in that slot? If that is the case - that is very disappointing (the specs for the machine do not say that) - but it does answer my question as to why a "non video" PCI express adapter doesn't work in that slot.
Exactly, the TV tuner is not a video card, I understand that, however, you need to check with your TV tuner manufacturer for information about compatibility using PCI express slot on your computer.
As mentioned the port was designed for video cards but I am sure you can installed other devices on the PCI express port, this is a compatibility issue.
