eVGA PCI-E card cause stop on startup

[xShrimp]

i bought a eVGA e-Geforce 7300GS w/ HDTV PCI-E, and when i placed it into my motherboard and booted it up, i got to the WinXP logo. At the logo, before the bar starts moving, i get a half a second stop error then a black screen and it restarts. when i put back the old video card (pci) it works fine when the pci-e card is OUT. any idea whats the problem?

heres a little info
it requires 300w+ power, i got 350
i have a gigabyte ga-8i945p-g motherboard with intel pentium d 820
1gb ram (2x 512 one pc4200 and one 3200)
33gb hdd with winxp
250gb hdd for storage

What is the other vid card? Type?

[xShrimp]

ATI pci Rage II , cant remember the specifics but its an OLD video card, that i used since my mobo has no video port

[CCT]

So, the new card is Nvidia and the old is ATI ?

[xShrimp]

yes the new card is eVGA (or nVidia) and the old is ATI
i gave a call to eVGA, and they told me to repair XP with the video card installed. im currently doing that right now

[xShrimp]

well the eVGA was right, he told me it was something about driver of ATI, gave me problems when i used an nVidia. so i just repaired it and it works perfectly now. thanks CCT for trying to help! =D
