Video card not recognized after changing Power supplies

  1. I changed power supplies in my computer so it turns on now but the monitor would not come on. I was using a flat screen with DVI connection to a ATI video card. My computer guy thinks it is a ATI 2400 xp. I have the computer plugged into the monitor via vga port on the mother board (Asus PLD2-VM) and the monitor works but I want to use DVI from the ATI video card obviously. How do I get the computer to recognize the ATI card again. I tried to enable PCI and PCIE in the bios under boot but that didnt work. I have disabled those again and need direction what to do in bios and control panel. The fan is running on the video card so I think it is functioning. How do I determin if the card IS working and or why the computer wont recognize it.

    What was the reason you changed the power supply? I presume the card worked before with the old power supply at one time. Perhaps the graphics card was damaged somehow when the old power supply failed.

    I changed pwr supplies cause the other one died. Perhaps it is dead ......Is there anything I can do to test this one before I buy another one. I would like to know for sure..

    Is there any way you can try your card in another PC or borrow another card and try it in your PC?
