Cpu wont boot with video card

i am trying to install a new video card (AGP) in my pc. it wont boot up when i put it in.
ive updated bios, chipset, tried 3 diff. cards. it only boots when i use an older card.
Motherboard is an ASUS P4P800x p4 3.0
any help?????

 

what card is it? what is the computer model number? ex: Dell Dimension # etc... If its custom build, what PSU are you using?

 

not sure the brand of psu but its 450 watts. ive tried 3 diff. cards that all work in another pc. also ive used a diff. psu from a comp that the card(s) work in and nothing.

 

have u tried this card in any other computers? if it doesnt work, return it and get a new card

 

i have tried this card in another and it works fine

 

You may want to download the manual for your motherboard
(if you do not already have it)

Could you please tell us the model of the graphics card you are trying to instal ?
