Your computer is a Business Lan computer and I believe it has one AGP slotx4/x8
Why are you using a PCI card that is much slower then AGP.

Go into your Bois and turn off, onboard Audio, If you are not using the soundblaster then remove the sound blaster.
I was going to say update your drivers, but when I found your drivers on gateway the newest drivers for your computer, was 2002, 7 years ago.
Name: MDP3880-W(U) PCI Modem- If you are not using dial up, you dont need this, and can be removed
Now, after looking at your DXdiag, and I know you dont want to hear this but, I dont think you will be able to play DDO on that computer. The computer is so outdated for current games, I dont think you could even get XP running correctly, in fact if you dont already have xp, dont get it, PLEASE dont get it for this computer. That hundred dollars could be used to get a fairly decent computer from Walmart that would run circles around your current computer.
Your memory is only PC133 133 Mhz, the cheapest computer at Walmart has 2gigs 667 MHz, and that computer is a dell and cost 428.00.
You have to understand im not saying this to be mean, I wish I could help ya, but in computer terms your computer is beyond help, and you should no longer put money into it.
Example would be car. well your computer(car) has 400,000 miles on it in computer terms, you would be better putting money down the drain, then to up grade.
Any money You would like to put into it save and buy a new computer, save yourself the headache in a year when you will not be able to do anything else on it excpect use it to log into the internet.
