What video card does my computer take?

Hey guys I use the HP Xeon XW6000 gaming computer, it has 5.6Ghz CPU, 2 GB of RAM and a Nvidia geforce4 XW420, I need to know what type of video cards this computer takes ie: AGP (I know it doesn't take AGP's because I tried inserting my 6600gt into this new pc and it bleeped 3 times and wouldn't load up the BIOS etc.) Please help :)|||hi mate

the problem when using the agp bus interface is that unlike the newer pci-express bus agp has around 6 or 7 different versions/types and since most of them are not backwards compatible it can be a minefield when upgrading a agp card in some cases

there are two most common agp types and the main one is the agp x8 and this uses a agp 1.5v slot....this is what any agp card made in the last 5 years would use allthough some also use the next most popular type the agp 3.3v slot and any card that supports this slot wont work in the agp 1.5v slot

however if we go further back there are other types of agp including agp universal and agp pro...with the universal having just one long slot were as the newer agp slots have two slots (0ne small and one large)

in regards to the post error beeps you are experiencing well this can be for many reasons ,and this includes incorrect bios video setting( change the default video settings in "intergrated peripherals" from onboard to agp....however you may also need to change the setting "init display first" which is a bios setting unique to agp based motherboards and informs the bios from what video device to boot from...obviously your option would be agp

another reason could be a problem with the actual agp bus(slot) and this can include incorrectly inserted or a cable trapped near the agp slot

and then theres also the agp aperture size,which should be set to either 64mb or 128mb(normally half the size of your cards memory)...try changing this and see if it helps

however one of the most common reasons for post beeps when installing a graphic card is because you havent connected the power connector to the card,and in the case of the 6600gt this is normally a standard 4pin molex connector...if you dont connect this the bios will alert you by beeping 3 times ( depending on bios version)....simply connect the required power connector and restart the pc

if you have connected the power connector to the card it may be that the power connector you are using is faulty so try using a alternative molex and see if that works

i hope this helps,any problems let me know

good luck mate !
