Installing graphics card ATI X1300?

Ok, first my specs...

I have an E-machines T3092

1gig PC-2700 ram

On-board Nvidia MX 64MB graphics card

AMD 64(single core)

I have been through tech support with ATI and E-machines both for much to long. First I talked to ATI, they stated I had some windows malfunction so I reinstalled my OS, followed the step by step instructions on how to install the AGP graphics card, I made sure I downloaded all drivers/chipsets for my E-machines and disabled my on-board graphics card before I installed the ATI card. The installation for the drivers for the ATI card was no problem. I rebooted to have everything take effect. I tried playing "Alien Shooter 2 Vengeance" and "Dynasty Warriors 4 Hyper" that was easily played using my on-board graphics card, and on Alien Shooter the screen turns black for 3 seconds and then kicks me back to the desktop while Dynasty tell me I dont have the latest DirectX3D software, yet I have installed DirectX lastest version. Whats going on? Please help! x.x

AGP is quirky like that. I'd buy a pci express motherboard.
