No video radeon 5450

hey tech experts,
i bought a radeon hd5450 512 ddr3 to put in my dad's pc but when i power it up no video shows. i reset the bios, still nothing. the card works bec when i swap it to my other pc and it shows video.
i put my XFX HD4890 - 1GB GPU that uses power connector on my dads pc and it works so the pci e works.

my dads pc has:
Antec 900 Case

Intel Core2Duo E8600 3.33GHz

cooler master extreme 500w

my pc.

  1. can someone delete this please, ie was acting crazy. sorry for the repost
  2. That's very strange.

    If a different video card works in your computer then this lower-powered one should work fine.

    You say the HD5450 works in a different computer as well...

    That doesn't really leave anything!

    *I can only assume you have hooked the monitor up to the graphics card. Other than trying a different PCIe slot I'm stumped.
  3. i tried that too, it still didnt work.
