As I've said before, I have changed the power supply. I took the the radeon and power supply out of a higher end computer and put it into this computer. It no longer has a 250 watt PSU. I've ran this card with this power supply for two years and had no problems. Here is the pc I got the card OUT of: HP Pavilion Elite HPE-400y Desktop PC Product Specifications HP Pavilion Elite HPE-400y Desktop PC - HP Customer Care (United States - English). That isn't the computer I'm have problems with, thats just where I got the card and PSU from.
^ OK, sorry I misunderstood, because earlier you said "As of right, both the Radeon 5450 and the GeForce are both connected to the motherboard." So you moved both the card AND the power supply to this computer then. What wattage is the PSU you're using?
You didn't find any BIOS setting to control the default graphics card, I take it. And you're sure you have the latest BIOS flashed for that computer? Actually, I just checked the specs, which say "Integrated video is not available if a graphics card is installed." To me that suggests installing a video card will override the default one automatically. So, maybe it's not sensing the new one properly.
I did notice in one of the photos of the Radeon HD 5450 512MB that there's an internal DVI socket. Connecting up a monitor should be external, and I see there is an external one. Maybe it's for the option where the motherboard is installed inside a single casing that has the LCD display.
One other thing... check the feedback for this video card on New Egg (link above). I spotted one of them that said this:
Just because this card worked with your other power supply in the other computer, doesn't mean it'll work fine in this current computer. The system may have different power requirements and tax the power supply enough so that there's not enough left for the card.Cons: Has issues with older motherboards. I couldn't get it to recognize the video card at all on my MSI 945GM3 motherboard. Some googling found some people have good luck, others get motherboard BIOS upgrades, and the rest of us are out of luck.
Cons: Review of this card claimed it was a low wattage video card. Upon arrival, system requirements mentioned on carton advised minimum power requirement was 400 watts. Being that my desktop only has a 250 watt power supply, this card wouldn't worrk for me.

Just wanted to be sure everyone could tell that I didn't just go out and buy a video card for an old computer lol. I upgrade the HPE with a new video card and PSU (which I had no problems with). And just figured that I would be able to put the 5450 and PSU into the old vista problem free. Guess I thought wrong :/. Wish there was some way to see if the cards faulty or not without removing my 6950 from the computer I use.
The only bios setting for the video card is choosing which slot to use for video. If I choose onboard then it uses onboard, if I chpose PCI, the. It uses PCI. If I choose PCI-E, then it uses PCI instead (or onboard if there is no PCI card available). As for making sure the bios is updated, I went to HP's page for this computer and don't see any BIOS updates, and I don't see any download links on the motherboard manufacturers website for downloading any updates of any kind.
Go to Control Panel, Programs and Features. Look for Microsoft .net framework. You should have at least 3.5 installed.
In regards to the Windows Updater, download the System Update Readiness Tool from Microsoft.com. Run it.
Which anti-virus program do you have installed.
The computer has Microsoft security essentials I believe. It doesn't work though.
Did you check .net framework, as I suggested?
Did you run the System Update Readiness tool?
I don't know what you mean by MSI isn't working. Is it in your system tray?
