We've purchased a HD5450 video card to work in an HP Compaq dc5700 small form factor computer with a 240w power supply. We've installed the card with no input on the monitor/tv we are connecting to the computer. Does that mean the card won't work on our older computer or do we need to upgrade the power supply?

The power supply isn't the problem; the DC5700 SFF does not have PCIe x16 support, just ADD2/SDVO, meaning that your particular graphics card (and most others) would not work in it.
