Thanks for your help FM, much appreciated.
I suspect I have only one PCI express slot which is being used by a Radeon X740XL card. The two empty slots (shorter than the slot the existing card is in) are marked PCI 1 & PCI 2 on the MB. As I said before, I have tried a standard PCI card and it caused the PC to crash intermittently.
I only want the extra digital video signal to feed a LCD TV with standard video. . I don't want to use the composite or scart socket as the quality isn't nearly as good as dvi feeding into the TV's HDMI input. I am not going to be playing heavy duty video games or Flight Sim etc so I didn't think I would need a particularly high spec card.
If I understand you correctly, I can't fit a PCI Express x1 in a standard PCI slot. Is this correct?
I have copied my system information input/output screen below with the hope you might be able to give me some other pointers.
